To create parallel structure in the sentence, which phrase would best replace the words "when plays are tragic"? plays that are funny are more popular than when plays are tragic.

plays that are tragic

Explanation:

Parallelism is arranging words of identical syntactical constructions in sentences.

We need a parallel, i.e. identical, construction for the phrase plays that are funny. Obviously, the word when does not help to create parallelism in the corresponding phrase. The solution is simple: we should repeat the beginning of the phrase and change the adjective.

The result is a sentence with a parallel structure:

Plays that are funny are more popular than plays that are tragic.
