Answer:
C
Step-by-step explanation:
Its asking a question that does not make sense to the listener. Comparing the question in answer option C to the other three answer choices, asking how long do you own a pair of shoes doesnt make sense. while the other questions ask stuff like what is the shoe size of the students, how may pairs do you have, or how much someone payed for something makes sense. But asking how long you own a pair of shoes does not. If the question were to be re worded, it would be something along the lines of: How long have you owned those pair of shoes?
