Hi there☺
I believe the answer is the second one, "<span>when the ideas in both clauses are closely related."
For example:
I really love cats; they are so cute and sweet.
Both are independent clauses, but are closely related ideas.
Hope this helped you.

It would be situational irony cuz of the irony of the situation. I’m pretty sure, but I could be wrong
