I think it's C.
Because, lemme put commas on each sentences....
(1) If you ask me, Jerry is a tennis whiz.
<span>(2) When she is worried, Lucille eats a lot. </span>
<span>(3) Jerry loves tennis, he plays everyday. </span>
<span>(4) Lucille bought a new tennis racket and brought it home. << Where should I put it?
</span>
So, (4) is automatically out of question. (1) and (2) seems okay with comma, but (3) is a little bit weird. (3) supposed to have 'and' in the middle, but it's not there. So, you can put semicolon there, to separate the words.
Are these meant to be titles of something (a book, movie, etc)? If so, then they should either be in quotation marks or in italics.
