Answer:
I believe the answer is A, which you chose.
Step-by-step explanation:
When talking about interrogations, you would usually think of someone asking questions while another one answers.
Declarative would be when someone makes a statement about something, like, "I am going to get that job!" Something like that.
The imperative is used to give commands and orders, so it wouldn't be that.
"In English grammar, an exclamatory sentence is a type of main clause that expresses strong feelings in the form of an exclamation, as opposed to sentences that make a statement (declarative sentences), express commands (imperative sentences), or ask a question (interrogatory sentences)."
(The last part is from go*gle, btw. I wanted to explain it better so I added it.)
Hope it helps!
