It's A
Me sorprende que me acuses de no tener confianza en ti
I would use
No, no me gusta la biblioteca.
I am hispanic and know spanish from an early age and this is the only one that makes sense.
P.S. In the question it is asking you if you like the library and 1 says Yes, I likes the library 2. Yes, you like the library 3. No I do not like the library and 4 No, you do not like the library, therefore number 3 is correct.
Sorry if that was a little to much
Igualmente because If u translate it “mucho gusto” is basically “nice to meet you” and “igualmente” means “you too” or in this case “nice to meet you too” which makes sense.
