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.

Which of the following professionals is three ranks senior to F?

To determine who is three ranks senior to F, we first need to establish the complete hierarchy of the eight professionals based on the given clues.

The sequence of ranks from highest (1) to lowest (8) is as follows:
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)

Step 1: Analyze the position of E, C, and D
We are given that C is immediately junior to E and immediately senior to D. This means E, C, and D must occupy three consecutive ranks in the order E → C → D.

Step 2: Determine the relationship between E and F
We are told that the number of individuals ranking senior to E is equal to the number of individuals ranking junior to F.
If Rank(E) represents the rank of E, then:
$\text{Rank(E)}-1=8-\text{Rank(F)}$
$\text{Rank(E)}+\text{Rank(F)}=9$

Step 3: Test possible placements for E, C, D
• If E holds Rank 1 (CEO): C holds Rank 2 (COO) and D holds Rank 3 (VP).
Then Rank(F) = 9 - 1 = 8 (Officer).
• Exactly two ranks separate A and B, where B is junior to Director (Ranks 6, 7, or 8). Since Rank 8 is occupied by F, B can be at Rank 7 (Manager). Two ranks separating A and B means Rank(A) = 7 - 3 = 4 (Senior Director).
• The remaining positions are Rank 5 (Director) and Rank 6 (Senior Manager) for H and G. Since G ranks junior to H, H must be at Rank 5 and G must be at Rank 6.
• This satisfies all conditions, including that H is not the CEO (H is Director).

Final Seating / Hierarchy 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

Conclusion:
F holds the rank of Officer (Rank 8).
Three ranks senior to F is Rank 8 - 3 = Rank 5, which corresponds to H (Director).

Therefore, the correct answer is H.
