Answer:
The answer would be C. How many of you listen to music for more than an hour each day?
Step-by-step explanation:
A is incorrect. Eliza wants to know how much time the students spend listening to music, she never specified for how long in the question and A. is asking if they listen to it for an hour when she just wants to know how many of them spend time listening to it overall.
B is incorrect. It's the same as A but with instead of asking other people, it seems like she would be asking one person. This makes it incorrect because we want to know how much time EVERYBODY spends listening to music when she is a person how long they listen to music a day.
C is correct. This option is asking how many people spend time listening to music for MORE than an hour. This option includes asking many people and asking for how long, unlike B and A.
D is incorrect. This option is asking for how many hours instead of one however, the option is not asking students but asking about the best musican. We need to know about the students not the best musican.
