Read the following information carefully and answer the questions given below

Some students attend the lectures and they all are arranged in three parallel rows such that row1 is north of row2 and row 3 is south of row 2. Each row has 8 seats. All the students face north direction. Some seats are vacant in each row. Twelve students- Allen, Fame, Emma, Alpha, Coco, Nick, Ivory, London, Olive, Unique, Jack and Den who attend the lectures are divided into two classes i.e., class A and class B. The students whose name start with a vowel belongs to class A and the rest belong to class B. The students in class A are sitting in the alternative seats from the second seat of Row 1 when counts from the left end according to the dictionary order followed by class B students who are sitting in reverse alphabetical order. After row 1, students are sitting in row 2 then in row 3 following the same rule. All students are sitting in the alternative seats only. Now the students sit around two circular tables i.e., Table1 and Table2 and all are facing the centre. Students belong to Class A sit in table 1and the rest of them sit in table 2.

Conditions for table 1: Allen sits opposite to the one who sits second from the left end in row 2. The one who sits right of olive in row 2 sits second to the right of Allen. Alpha doesn’t sit adjacent to Olive and sit opposite to Emma.

Conditions for table 2: London sits second to the right of the one who sits adjacent to Unique. The one who sits at extreme end sit third to the left of London. Jack sits opposite to Den and doesn’t sit adjacent to Nick.

Who among the following sits fourth to the left of London in rows-based arrangement?

The correct option is Unique.

Step 1: Identify and categorize the students into Class A and Class B
We have 12 students: Allen, Fame, Emma, Alpha, Coco, Nick, Ivory, London, Olive, Unique, Jack, and Den.
• Class A (Names starting with a vowel): Allen, Alpha, Emma, Ivory, Olive, Unique.
• Class B (Names starting with a consonant): Coco, Den, Fame, Jack, London, Nick.

Step 2: Understand the linear seating rules
• There are 3 parallel rows (Row 1 is North of Row 2, Row 3 is South of Row 2).
• Each row has 8 seats numbered 1 to 8 from left to right.
• Students sit ONLY in alternate seats, starting from the 2nd seat of Row 1 (i.e., seats 2, 4, 6, 8 in each row).
• Total alternate seats available: 4 seats per row × 3 rows = 12 alternate seats.
• Ordering sequence: First Class A students in alphabetical (dictionary) order, followed by Class B students in reverse alphabetical order, filling Row 1, then Row 2, then Row 3.

Step 3: Arrange Class A students in dictionary order
Class A students in alphabetical order are:
1. Allen
2. Alpha
3. Emma
4. Ivory
5. Olive
6. Unique

Step 4: Arrange Class B students in reverse alphabetical order
Class B students in reverse alphabetical order are:
7. Nick
8. London
9. Jack
10. Fame
11. Den
12. Coco

Step 5: Place students in the alternate seats across Row 1, Row 2, and Row 3
• Row 1 (Seats 2, 4, 6, 8):
- Seat 2: Allen
- Seat 4: Alpha
- Seat 6: Emma
- Seat 8: Ivory

• Row 2 (Seats 2, 4, 6, 8):
- Seat 2: Olive
- Seat 4: Unique
- Seat 6: Nick
- Seat 8: London

• Row 3 (Seats 2, 4, 6, 8):
- Seat 2: Jack
- Seat 4: Fame
- Seat 6: Den
- Seat 8: Coco

Step 6: Determine who sits fourth to the left of London in the row-based arrangement
• London is seated at Seat 8 in Row 2.
• Moving to the left of London along the occupied/alternate seats in Row 2:
- 1st to the left: Nick (Seat 6)
- 2nd to the left: Unique (Seat 4)
- 3rd to the left: Olive (Seat 2)
• Counting seat positions continuously: 4 positions to the left of Seat 8 is Seat 4, which is occupied by Unique.

Therefore, Unique sits fourth to the left of London.
