Hi there!
The sentence that would need a semicolon is the first sentence, Jerry loves tennis he plays everyday. Here's the corrected sentence: Jerry loves tennis; he plays everyday. The semicolon separates the two ideas in this sentence. Since this is the only sentence that has two ideas in it, this sentence needs a semicolon.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
