A for me as well. Since the question does not ask for specific values of x, y, z, (1) is sufficient.

Using (1), we know 70 = 2*5*7. Only one combination since all integers must be greater tha 1. (1) is sufficient.

Using (2), we don't know if x/yz = 7/10 or 70/100 or 700/1000 etc...So (2) is sufficient.

Ans: A
