Question

Select the correctly punctuated sentence. Its going to be a long wait the nurse confided. It's going to be a long wait, the nurse confided. "Its going to be a long wait," the nurse confided. "It's going to be a long wait," the nurse confided.

Answer 1

The last one is the correct answer.
It is "It's going to be a long wait," the nurse confided.
When someone is speaking, there needs to be quotation marks. Also, It's needs an apostrophe because that makes it stand for "It is"
So the last answer is the right one.
