Answer:
What my father has <em><u>to do is wear a uniform</u></em> and check everyone's identity.
Explanation:
A cleft sentence is a sentence that is restructured in such a way that the parts of the sentences are moved from their original positions for more emphasis. In this type of sentence, the emphasis is made to make it clearer to the listener.
In the given original sentence, the structure is <em>"my father has to wear a uniform and check everyone's identity."</em> And in making it into a cleft sentence with the "wh-" construction, we can write the sentence as
What my father has <em><u>to do is wear a uniform</u></em> and check everyone's identity.
Letter Choice A. Because you're physically doing it.
