Yoga has become a very popular type of exercise, but it may not be for everyone. Before you sign yourself up for a yoga class, you need to examine what it is you want from your fitness routine.

Choices d and e are also not supported since the paragraph doesn't tell us whether yoga is good for both body and mind or what people think about it.
