This question is testing your knowledge of verb tenses. The sentence is talking about a time in the past when someone used to enjoy patronage. The question is asking which word or phrase best fits in the blank space.

Option A is "would". This is the past tense of "will" and can be used to talk about repeated actions in the past, but it doesn't fit well in this sentence.

Option B is "will". This is the future tense of the verb "to be", and it doesn't make sense to use it in this sentence because we are talking about a time in the past, not the future.

Option C is "used to". This is the correct answer. "Used to" is used to talk about past habits or actions that are no longer true in the present.

Option D is "could". This is the past tense of "can", and it doesn't fit well in this sentence.

So, the correct answer is Option C, "used to". This means that in the past, the person enjoyed patronage, but this is no longer true in the present. To learn more about verb tenses, please see the relevant sections of the recommended textbooks.
