Select the option that expresses the given sentence in passive voice.
You must send applications to the university before December 30.
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Applications must be sent to the university before December 30.
The original sentence is in active voice with a modal verb 'must' indicating necessity: You must send applications...
In passive voice, the subject (applications) should receive the action, and the modal verb 'must' stays the same but is followed by 'be' + past participle ('sent').
So, the correct passive form is: Applications must be sent...
Why the other options are incorrect:
Option 1: 'Applications are to be sent...' is grammatically correct but changes the tone slightly. It expresses obligation but not as strongly as 'must'.
Option 2: 'Applications has to be sent...' is incorrect because 'applications' is plural and should take 'have' instead of 'has'.
Option 4: 'Applications were to be sent...' suggests a past obligation or plan, which changes the original meaning that is in the present/future.
