Hi how are you. i am 16 yrs old.
The fourth option
sentence fragments cannot stand on its own even though it is punctuated. an example of this is: after the party.
The answer is C. The story never mentioned A, B, or D.
The answer is C. Because it gave the most excitement to the sentence cuz its like hurry up cuz something is coming or they late etc.
Hope This Helps !
