Final answer:
The question is the setup for a joke where the punchline is 'It was a soft drink', which is a play on words referring to non-alcoholic beverages. The correct option is C.
Step-by-step explanation:
The question 'Did you hear about the guy who got hit in the head with a can of soda?' is one that seems to be seeking a punchline to a joke rather than a serious answer.
The question is intended to be humorous and the correct response would usually be the one that is the punchline.
In this case, the answer 'It was a soft drink' is a play on words and is the punchline since 'soft drink' refers to a non-alcoholic beverage, which would be less harmful compared to a hard object.
