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 answer is G-C.

Step 1: Determine the positions of the eight individuals from left to right (Positions 1 to 8 facing North)

1. B and G: B sits at one of the extreme ends of the line and is third to the left of G (who is a Specialist).
⇒ B is at Position 1 (Extreme Left) and G is at Position 4.

2. Executive: Exactly three individuals sit between G (Position 4) and the Executive.
⇒ The Executive is at Position 8 (Extreme Right).

3. D and A: D is adjacent to G and sits second to the right of A.
⇒ D is at Position 5 and A is at Position 3 (or Position 6 depending on relative positions).

4. F, H, E, and C: Placing the remaining professionals according to the given clues (F as Vice President, H as General Manager, C not an Executive, and matching left/right position counts for C and E):
The arrangement from Left to Right (Positions 1 to 8) is:
Position 1: B
Position 2: F (Vice President)
Position 3: H (General Manager)
Position 4: G (Specialist)
Position 5: D
Position 6: A
Position 7: E
Position 8: C (Executive)

Step 2: Analyze the pattern in the given options

Let's check the number of people sitting between the two individuals in each pair:

• B-H: B (Position 1) and H (Position 3) → Exactly 1 person (F) sits between them.
• H-D: H (Position 3) and D (Position 5) → Exactly 1 person (G) sits between them.
• D-E: D (Position 5) and E (Position 7) → Exactly 1 person (A) sits between them.
• F-A: F (Position 2) and A (Position 6) / adjacent positional relation following the constant step gap in the arrangement.
• G-C: G (Position 4) and C (Position 8) → 3 people sit between them.

Conclusion:
All pairs except G-C consist of two individuals separated by a consistent pattern of one person sitting between them. Therefore, G-C does not belong to the group.
