A scientist is trying to find a cure for the common cold using four ingredients. He can choose from the stable chemicals A, B and C and the unstable chemicals W, X, Y and Z, In order for the formula not to explode, there must be two stable chemicals in it Also, certain chemicals cannot be mixed because of their reaction together. Chemical B cannot be mixed with Chemical W. Chemical Y cannot be mixed with Chemical Z.

. If the scientist calculated that Y is the most important chemical and must be used in the formula, which other ingredients must be a part of the cure?
A.A, B and Z
B. B, C and Z
C. A, B and W
