Correct Answer: C
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.
Choice A is incorrect because we cannot deduce the relationship between A and D. similarly, Choice B is incorrect because we cannot deduce the relationship between B and F. Likewise, Choices D and E are incorrect. Choice C is correct (see above)
