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.

Let's analyze the given information step-by-step to determine the complete ranking hierarchy of the eight professionals.

1. Hierarchy Structure (from Senior/Highest rank 1 to Junior/Lowest rank 8):

1. Chief Executive Officer (CEO)
2. Chief Operating Officer (COO)
3. Vice President (VP)
4. Senior Director (SD)
5. Director (Dir)
6. Senior Manager (SM)
7. Manager (Mgr)
8. Officer (Off)

2. Analyzing the Clues:

• B holds a position junior to Director (Dir). Therefore, B can be placed at Senior Manager (6), Manager (7), or Officer (8).

• Exactly two ranks separate A and B. So, A must be senior to B by 3 positions (Rank of A = Rank of B - 3):

- If B is at SM (6), then A is at VP (3).

- If B is at Mgr (7), then A is at SD (4).

- If B is at Off (8), then A is at Dir (5).

• C is immediately junior to E and immediately senior to D. This means E, C, and D must occupy three consecutive positions in that exact order (E → C → D).

• The number of individuals senior to E equals the number of individuals junior to F.

• H does not hold the rank of CEO (1), and G ranks junior to H (H is senior to G).

3. Determining the Positions:

Let's test the consecutive block E-C-D:

If E is at CEO (1), C is at COO (2), and D is at VP (3):
- Senior to E (Rank 1) = 0. Therefore, Junior to F must be 0, placing F at Officer (8).
- Now, A and B need positions separated by 2 ranks.
- If B is at Mgr (7), then A is at SD (4).
- The remaining ranks to fill are 5 (Dir) and 6 (SM) for H and G.
- Since H is senior to G, H takes Dir (5) and G takes SM (6).
- H is at Dir (5), which satisfies the condition that H is not CEO (1).

Final Arrangement:

1. CEO: E
2. COO: C
3. VP: D
4. SD: A
5. Dir: H
6. SM: G
7. Mgr: B
8. Off: F

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