Answer 2

Here good night is the wrong part of the sentence.

Good night means one is bidding adieu to another person.

But in the next sentence, that person starts having a conversation.

And the next part usually starts the conversation.

Generally, good evening is said at the beginning of a conversation.

And good night is used to end the conversation.

Hence, in the above mentioned sentence,

Good night won't be applicable.
