This question says Madsen is evaluated alone. That means that there are two candidates who must be evaluated alone: Madsen and Kent.
Smith always evaluates at least two candidates, and Ullman always evaluates Grant. So that means that Rao and Tipton must evaluate Madsen and Kent.
Madsen and Kent are interchangeable on this question, I’ve drawn a line to show this. I use this type of line whenever an entire group is interchangeable:
The next step is logically difficult. There are four people left to place: FL, H and Inman. H and Inman can’t go together.
That means that one of H/I will go with FL. So these four variables will be distributed in a group of three and a group of one.
We need at least two people to go with Smith. So the group of three, the group with FL, must be evaluated by Smith:
Hong and Inman are interchangeable between Smith and Ullman.
B is CORRECT. Lopez must be evaluated by Smith.
Notice that all the other answers mention Madsen, Kent, Inman and Hong. These four variables are all interchangeable with another variable on this question, so they could never be the right answer.
