Read the following information and answer the following questions.

Eight persons whose names begin with A, B, P, C, D, O, Q, and E are sitting around a circular table facing inward. Persons, whose names start with a vowel, do not sit adjacent to each other.
A sits 3rd to the right of D. Two persons sit between P and A. B sits adjacent to O, who sits 4th to the right of E. Q sits 3rd to the left of O.

Who is sitting at the immediate left of B?

The correct option is A.

Step-by-Step Logic and Seating Arrangement:

1. There are 8 persons sitting around a circular table facing inward: A, B, P, C, D, O, Q, and E.

Vowels in these names are: A, E, O.

Consonants are: B, C, D, P, Q.

Rule: Persons whose names start with a vowel (A, E, O) cannot sit adjacent to each other.

2. "A sits 3rd to the right of D."

Let us fix D at position 1 (numbered 1 to 8 in clockwise direction).

Since everyone is facing inward, moving to the right is moving counter-clockwise.

Position 1: D

Position 4: A (3rd to the right of D)

3. "Two persons sit between P and A."

Moving counter-clockwise from A (pos 4): pos 5, pos 6, so P would be at pos 7.

Moving clockwise from A (pos 4): pos 3, pos 2, so P would be at pos 1 (which is already occupied by D).

Therefore, P must be at Position 7.

4. "O sits 4th to the right of E."

In an 8-person circular table, sitting 4th to the right (or left) means sitting directly opposite each other.

So, O and E are directly opposite each other.

Since A, E, and O are vowels, none of them can sit next to each other.

A is at Position 4. Thus, neither Position 3 nor Position 5 can be occupied by E or O.

The available opposite pairs remaining are (Position 2, Position 6) and (Position 3, Position 7 - but 7 is P, not an opposite pair slot open for both). Position 8 and Position 4 is not available as 4 is A.

So E and O must occupy Position 2 and Position 6.

5. "Q sits 3rd to the left of O."

If O is at Position 6: 3rd to the left (clockwise) of Position 6 is Position 3. This means Q is at Position 3, and E is at Position 2.

If O were at Position 2: 3rd to the left of Position 2 is Position 7 (which is already occupied by P). Hence, O cannot be at Position 2.

Therefore:

Position 6: O

Position 2: E

Position 3: Q

6. "B sits adjacent to O."

Positions adjacent to O (Position 6) are Position 5 and Position 7.

Since Position 7 is occupied by P, B must be at Position 5.

7. The remaining empty position is Position 8, which must be occupied by C.

Final Seating Arrangement (Clockwise starting from 1 to 8):

1: D

2: E

3: Q

4: A

5: B

6: O

7: P

8: C

Question: Who is sitting at the immediate left of B?

Since everyone faces inward, immediate left of a position moves in the clockwise direction.

B is at Position 5. Going clockwise to the immediate left of Position 5 leads to Position 4, which is occupied by A.
