Step-by-step explanation:

Answer 2

A sentence fragment is a part of a sentence - it cannot exist on its own, but rather has to be included within a larger sentence in order to make sense. Having this in mind, the correct answer is Watching a scary film with my friends at the theater.
This fragment doesn't have a verb at all, which is why it is a fragment rather than a clause, like the other options.
