Correct Answer: D
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.
Choices A, B, C and E are incorrect answers because we cannot deduce a relationship between the pairs in each choice. Choice D is correct answer because of the following: A is the immediate superior of B; E is a superior of B. thus E must be superior to A.
