Punctuations are used in a sentence to organize and structure it properly. Moreover, it is used to create clarity and sense or to stress in a sentence. For example quotation marks " ", full stop (.), commas and so on.
Commas are frequently used punctuation in a sentence, hence they are used to create a short pause in a sentence.
In the above sentences, the sentence which is punctuated correctly is C. After they rested a few days, the aliens revived sufficiently to explore.
When starting with the dependent clause, the sentence is punctuated after the dependent clause. In the above sentence dependent clause is <em>“After they rested a few days”</em>, hence as compared to other sentences it is punctuated correctly.

I'm assuming you're asking what a sentence and sentence fragment is, a sentence is a proper line of words, involving at least a subject and predicate.
A sentence fragment is an incomplete sentence that doesn't finish what it is completely stating.
Examples- Uncle John ate. (Ate what?) Until it left. (What left? There is no subject, either.)
Hope it helped, Tiara
