I'm interested! I think Discord works best since you can share questions and screenshots and such pretty easily.

Answer choice B says "more than once a week". If you negate that, it is not more than once a week. So it COULD mean 0, but it could also mean 1. Therefore, you should eliminate the answer because why does practicing yoga more than once a week have to do with the argument? The premise stated only once a week was enough to be effective on top of the counseling.
