Answer 1

there are women in the class who work and attend college

"In the class" is the correct answer.

Answer 2

The preposition specifically is “in”
How I think about a proposition is everything a squirrel can do to a tree.
It can go in, above, across, against, around, behind, down, inside, in, etc.
