Read the given information carefully and answer the question that follows.

Eight professionals hold different positions, namely Chief Executive Officer (CEO), Chief Operating Officer (COO), Vice President (VP), Senior Director (SD), Director (Dir), Senior Manager (SM), Manager (Mgr), and Officer (Off) in an organization. The hierarchy of their seniority is in the same sequence as listed, where CEO represents the highest rank and Officer represents the lowest rank.

Exactly two ranks separate A and B, where B holds a position junior to Director. C is immediately junior to E and immediately senior to D. The number of individuals ranking senior to E is equal to the number of individuals ranking junior to F. G ranks junior to H, and H does not hold the rank of CEO.

Who among the following holds the senior-most rank?

The correct option is E.

Step-by-Step Explanation:

Let us list the eight positions in descending order of seniority (from rank 1 to rank 8):

1. CEO (Chief Executive Officer)

2. COO (Chief Operating Officer)

3. VP (Vice President)

4. SD (Senior Director)

5. Dir (Director)

6. SM (Senior Manager)

7. Mgr (Manager)

8. Off (Officer)

Analyzing the clues step by step:

1. Positions of B and A:

B holds a position junior to Director (Dir, rank 5). So B can be SM (rank 6), Mgr (rank 7), or Off (rank 8).

Exactly two ranks separate A and B.

If B is SM (rank 6), A could be VP (rank 3).

If B is Mgr (rank 7), A could be SD (rank 4).

If B is Off (rank 8), A could be Dir (rank 5).

2. Positions of C, E, and D:

C is immediately junior to E and immediately senior to D. This means E, C, and D form a continuous block of three consecutive ranks in the order: E → C → D.

3. Symmetry between E and F:

The number of individuals ranking senior to E is equal to the number of individuals ranking junior to F.

Let's check the possible position blocks for E, C, D:

- If E is CEO (rank 1), then C is COO (rank 2) and D is VP (rank 3).

- Since 0 people are senior to E, 0 people must be junior to F, placing F at Off (rank 8).

- Remaining positions for A, B, H, G: Ranks 4, 5, 6, 7.

- We know B is junior to Dir (5, 6, 7, 8). With rank 8 occupied by F, B could be rank 6 or 7.

- If B is SM (rank 6), A must be VP (rank 3), but rank 3 is occupied by D. Contradiction.

- If B is Mgr (rank 7), A must be SD (rank 4). This works! So B = Mgr (rank 7) and A = SD (rank 4).

- Now remaining open ranks are 5 (Dir) and 6 (SM) for H and G.

- We are given G ranks junior to H, so H = Dir (rank 5) and G = SM (rank 6).

- H is Dir (rank 5), which satisfies "H does not hold the rank of CEO".

Let us verify the complete hierarchy:

1. CEO: E

2. COO: C

3. VP: D

4. SD: A

5. Dir: H

6. SM: G

7. Mgr: B

8. Off: F

All conditions are satisfied:

- Hierarchy order: E, C, D, A, H, G, B, F

- B (Mgr, 7) is junior to Director (5).

- Exactly two ranks separate A (4) and B (7): 5 and 6.

- C (2) is immediately junior to E (1) and senior to D (3).

- 0 senior to E (1), 0 junior to F (8).

- G (6) is junior to H (5), and H is not CEO.

Therefore, E holds the senior-most rank (CEO).
