Fill in the Blanks
We offer a wide ....... of classes in this school.
For me a wide variety of classes imply that we have various classes (in different subjects) and wide choice of classes imply that you have a lot of classes to choose from (and attend in). But the questions of the book in which I found this question have one valid answer and I don't know which one is right and I am not native so I cannot be sure about the feeling I get from each answer.
So, which answer is right (or more appropriate)?
