It clearly boils down to B and E. B may be confusing at first but if you take the time to analyze it, you will see that it is wrong. Say there are 100 candidates and 15 are women. Whether or not those 15 women run against each other will not justify the reason why there are so few women running. On the other hand, E explicitly mentions the cause
of women not running as a being financial issue. Let's say there were 50 women willing to run but that because of financial constraints, only 15 could run, then can we say that there were few women who wanted
to run? No. 50 actually wanted to run. E is best as it weakens the argument.
