Answer:
(C) should not
Step-by-step explanation:
If you put each phrase into sentence format, "should not" is the only one that would make sense.
A) "You does not waste any more time." (Doesn't make sense, therefore (A) is not correct.)
B) "You were not waste any more time." (Doesn't sound right, therefore (B) is not correct.)
D) "You is not waste any more time." (Also doesn't make sense, therefore (D) is not correct.)
C) "You should not waste any more time" (This one sounds right if you say it out loud and looks right on paper, therefore (C) is your answer).
I hope this helps!!
