Yoga can help strength muscles and increase flexibility. Because muscle strength is more important to most people, yoga teachers should choose to focus primarily on exercises that strengthen muscles.

Which of the following is an assumption on which the argument depends?

A) Some yoga exercises are better for beginning students, while others are more appropriate for advanced partitioners.

B) Different teachers are able to interpret yoga poses in different ways.

C) Even if a practice has two benefits, teachers should focus on the one that the majority of people find important

D) If an exercise is designed primarily to strengthen muscles, that exercise will not also increase flexibilty.

E) Yoga teachers are not concerned with the desire of their students.

Why not B? The argument talks about exerciseS,so the author assumes that the teacher are able to perform different poses.
In relation to C. The argument just mentions that the teacher should focus on excersises that strengthen muscles. Just that, we cannot assume that he or she should focus on one of the benefits if an exercise has both. We cannot assume that it is possible to focus on one benefit if the exercise has both.

I believe this question is not good. What do you think?
