From Statement 1 , we know there are 18 Members (Girls) .
Not sufficient to answer girls who are members of both group .

From Statement 2 , we know that there are 9 Girls in Diving team and 12 girls in swim team .
However , Not sufficient to answer girls who are members of both group .

Combining the statement 1 and 2 .
We know that 18 = 9 + 12 - Girls in Both team
Girls in Both team = 3

Answer is C .
