Answer 1

We have cool nights right now here in western New York state, and the cactus, out on the porch, likes this cooling time, and it is setting flowers now.  Be careful though, if frost is predicted, take it inside for that night.  These cacti seem to like alternating cold and warmth (the warm days) in order to bloom.  Best wishes to you.

Answer 2

Christmas cactus is an indoor plant, so it's light sensitive, not temperature sensitive.

"C" would work well.
