I'm a bit confused as to why (A) is the right answer.
In choice (A), the athletes continue to employ training techniques EVEN THOUGH they know that the techniques are unlikely to be effective (or am I interpreting the answer choice wrongly?)
This seems to deviate from the attitudes of plaintiffs who pursue sex discrimination lawsuits. Lines 21-22 say that "plaintiffs who believe that their cause is just and THAT THEY WILL PREVAIL are not swayed by such evidence" leading me to believe that they DO believe the techniques will be effective, which is different from what the athletes in choice (A) believe.
