my answer is A.
we need to find if P(W)=p is > 1/2 or not
Prob of both being women = 1 - {p(of two men) + p(of 1 M , 1W)}
p = 1 - (x+y)
S1 ) Sufficient - from this we can tell if p is > 1/2 or not
because assuming 6 w 4m, 7w 3m, etc.,
we can calculate x and y and tell is p>1/2 or not
S2 ) Insufficient - coz we are given multiple values for x, but no way to know y
