Definition:Sentence fragments are groups of words that look like sentences, but aren't.
Example:Which is why I cried.
This sentence could be corrected by removing "which is why." The sentence "I cried." is a complete sentence. I is the subject, cried is the action.The sentence could also be corrected by joining it with an independent clause. I was sad, which is why I cried.
<em>Once the pollen grain is recognized and hydrated, the pollen grain germinates to grow a pollen tube. There is competition in this step as many pollen grains may compete to reach the egg. The stigma plays a role in guiding the sperm to a receptive ovule, in the case of many ovules.</em>

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.
sentence 3, there should be a comma after hugging.
