PAA, so kasha reisha aseifa. I would answer, chisurei mechs’ra, v’hochi kotoni: we want to be MKs, but that won’t fly, so let’s make up reasons why it benefit the tzibbur, d’haynu, (v’chulhu).
Also, none of the three reasons make sense.
The first reason presupposes that male MKs would otherwise be learning. Meiheicha teisi. Furthermore, it’s ridiculous to assume that those clamoring for female charedi representation are motivated by wanting more men in the Bais Medrash.
The second and third reasons assume that charedi men don’t value women’s opinions, and in fact, don’t value them at all. Aside from being profoundly insulting to charedi men, to assume that the male dominated charedi political parties would wake up one morning and say, “You know, they’re right, we hate women, so let’s make them MKs”.
