Answer:
C: Nobody's
Step-by-step explanation:
The bolded words "Nobody" and "is" in the sentence should be contracted as option C presents: The word "nobody', which requires a singular verb, in this case the verb 'is", and contracting them, it becomes: "nobody's". The apostrophe ( ' ) is used to show that the letter "i" is left out. The same is used for other contractions: I am/ I'm; They are/They're; She is/she's etc.
