None of the answer choices in anywhere close to right, because you didn't use parentheses correctly.

(y^2*10^-4)*(z*1000000)/(y*0.0001)*(z*10^6)

Each expression in parentheses is a single number. The operations in the expression, left to right, are multiply, divide, and multiply. Those operations have equal priority; they are performed in order, left to right.

The expression you probably meant to show is

(y^2*10^-4)*(z*1000000)/((y*0.0001)*(z*10^6)), or

In this (probably) correct form, it is easy to see that the expression is equal to just "y".

But that is not one of your answer choices; so it appears the problem is flawed, or you have not shown it correctly.
