a vector v with the default constructor, another vector w with a one-argument constructor to a size of 11, and insert 3 elements into each of these vectors with push_back(), then the size() member function will return__for v and__for w.

(A) 11 for v and 3 for w
(B) 0 for v and 0 for w
(C) 0 for v and 3 for w
(D) 3 for v and 11 for w
