Thanks. OA is B.
I am somewhat weak in DS because it always takes me longer time to figure out.
Trust but verify.

B for me as well.

approach is similar as others.

This is not one of the easy DS q.
I notice a GMAT pattern for tough questions ie.
one stmt is tough and the other is easy.

Curious. what is the source?
