A sentence fragment is a group of words that looks like a sentence, but isn't. To be a sentence, a group of words must have at least one independent clause ( a group of words that contains a subject and a verb and can stand on its own as a complete thought). Taking this into account, the answers to your questions would be the following ones:
1) B (Near the old pharmacy)
2) B (When she is on break from school)
3) C (Trying to feel ready for opening night)
4) A (Especially if you have children)
5) B
6) C
7) C
8) D
9) B
10) B
