Hello!

The subject is the topic that is being talked about so, "when" is not a topic, it's a question so that is not it. "This" is obviously not a subject either, so that's out. The question is about parades, and it is asking when it is which is summer. So that leaves you with Parades as that is what the question is about.

I hope this helped,

I am, yours most sincerely,
