Two elements, X (Atomic mass 16) and Y (Atomic mass 14) combine to form compounds A, B and C. The ratio of different masses of Y which combines with fixed mass of X in A, B, and C is 1:3:5 If 32 parts by mass of X combines with 84 parts by mass of Y in B, then in C 16 parts by mass of X will combine with
A. 14 parts by mass of Y
B. 42 parts by mass of Y
C. 70 parts by mass of Y
D. 82 parts by mass of Y
