Correct option is C
Explanation of the Correct Answer:
· The given sentence is in
active voice:
·
Subject (You) + Verb (must send) + Object (applications to the university).
· When converting to
passive voice, the object
"applications" becomes the
subject.
· The correct structure is:
·
"Applications must be sent to the university before December 30."
Other options:
·
(a) "Applications has to be sent" → Incorrect because "Applications" is plural, so "has" should be "have."
·
(b) "Applications were to be sent" → Incorrect because "were to be sent" implies past obligation, while the original sentence is in present/future.
·
(d) "Applications are to be sent" → Incorrect because "are to be sent" changes the modal verb
"must" to a less forceful obligation.
Thus, the correct answer is
(c) "Applications must be sent to the university before December 30."
