Question

What part of the novel contains the revealed secrets and ties up all the loose ends? A. resolution B. rising action C. falling action D. denouement

Answer 1

I see the confusion.  Resolution happens when the character solves the main problem/conflict or someone solves it for him or her. The Denouement is the very ending.

I would choose A. Resolution.

Answer 2

The answer is A. resolution. Resolution  means  to make a decision and find a solution to whatever the conflict is.
