Correct Answer: E
Explanation:
The best way to approach a situation like this is to describe the relative ranks of E, A, B, F , C and D as follows:
- higher ↑:E F A C
- Lower ↓:B D
Note that since A is the immediate superior of B and since B works under E, E must be superior to B. since F is superior to C and C is superior to D, F is superior to D.
If B is superior to F, then the order of ranks is E > A > B > F > C > D
Thus B is superior to D, A is superior to C, and E is superior to F.
