The answer is: C. The children ran in every direction. Glad to be outside.
- The sentence fragment is "glad to be outside" because it is written as a sentence but, in fact, it is a dependent clause which can not stand alone, it requires at least one independent clause (with subject and verb such as <em>the children ran in every direction</em>) to be considered a sentence, or, as the other answer options illustrate, the dependent clause needs to be followed or preceded by a comma.
