There was a long line at the grocery store, and this was very inconvenient for the customers.
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 !
I believe the right answer would be C) monitor.
Monitor can be a noun; "I have many monitors."
Or a verb; "I'll be able to monitor that soon."
A and b are incorrect and c is correct!
