Which one of the following, if true, most seriously weakens the company president’s argument?
(A) Some of the company’s sales representatives completed a degree in engineering while working for the company.

Megann, the president of the company argues that the best sales reps (i.e., a SMALL subset of all sales reps) have a degree in engineering. Choice B states that MOST (i.e., a LARGE subset of sales reps) already have a degree in engineering. This means that there are many sales reps with a degree in engineering that are not best performers. Hence choice B weakens the argument.

I don't understand how choice B weakens the president's argument, when it just seems to summarize his first statement. Help?

How do you know it's small/big subset? The passage in no way mentions that!

Saeed, please read the explanation carefully. The passage does not mention that, but Choice B mentions "Most".
