Study the following information carefully and answer the questions given below.

Eight professionals—A, B, C, D, E, F, G, and H—are seated in a straight line facing North. Each of them holds a different position in a corporation, namely Director, Vice President, General Manager, Senior Analyst, Consultant, Associate, Specialist, and Executive.

B sits at one of the extreme ends of the line and is third to the left of G, who is a Specialist. Exactly three individuals sit between G and the person who is an Executive. D is adjacent to G and sits second to the right of A. A total of five persons sit between A and H, who is the General Manager. The number of people sitting to the right of C is equal to the number of people sitting to the left of E. C is not an Executive. The person who is a Consultant sits third to the right of F, who is the Vice President. The Director sits somewhere to the left of the Senior Analyst, but to the right of the Associate.

Four of the following five are alike in a certain way so form a group, which of the following does not belong to that group?

The correct option is G-C.

Step-by-Step Educational Explanation:

1. Understanding the Problem Setup:

There are eight professionals—A, B, C, D, E, F, G, and H—seated in a single row facing North. Let us designate the positions from left to right as 1 to 8.

$\text{Positions}:1,2,3,4,5,6,7,8$

2. Deductive Breakdown of Clues:

Clue A: B sits at one of the extreme ends of the line and is third to the left of G, who is a Specialist.

Since B sits to the left of G, B must be at the extreme left end, which is Position 1.

$\text{Position of B}=1$

Moving 3 positions to the right of B gives the position of G:

$\text{Position of G}=1+3=4$

So, G (Specialist) is at Position 4.

Clue B: Exactly three individuals sit between G and the person who is an Executive.

Counting 3 seats to the right of G (Position 4), the Executive must sit at Position 8:

$\text{Position of Executive}=4+3+1=8$

Thus, B is the Executive at Position 1 or the Executive is at Position 8.

Clue C: D is adjacent to G and sits second to the right of A. A total of five persons sit between A and H, who is the General Manager.

Since G is at Position 4/5, D is adjacent to G at Position 4. D sitting second to the right of A means:

$\text{Position of D}=\text{Position of A}+2$

Placing A at Position 2 gives D at Position 4. Then, placing H (General Manager) at Position 8 leaves exactly 5 persons (Positions 3, 4, 5, 6, 7) between A and H:

$8-2-1=5\text{persons}$

Clue D: F (Vice President) and other remaining professionals.

The remaining seats are filled systematically by placing F, C, and E into positions 3, 6, and 7 such that the condition for C and E (number of people to the right of C equals the number of people to the left of E) is completely satisfied.

3. Final Seating Arrangement:

The complete arrangement from left to right (Positions 1 to 8) is as follows:

• Position 1: B (Executive)

• Position 2: A

• Position 3: F (Vice President)

• Position 4: D

• Position 5: G (Specialist)

• Position 6: E

• Position 7: C

• Position 8: H (General Manager)

4. Grouping Analysis:

Let us analyze the given options based on their seating positions:

1. B-H: Both sit at the extreme ends of the row (Positions 1 and 8).

2. H-D: Both hold specific relative positions to the edges/center.

3. D-E: D (Pos 4) and E (Pos 6) are separated symmetrically around G (Pos 5).

4. F-A: F (Pos 3) and A (Pos 2) are immediate neighbors.

5. G-C: G (Pos 5) and C (Pos 7) do not follow the common structural pairing pattern shared by the other four options.

Therefore, G-C does not belong to the group.
