Please answer ASAP! Given a right triangle ABC, we have found that a2=cr and b2=cq. Which of the following steps needs to be performed to result in the Pythagorean Theorem?

a) Add the left sides and the right sides of each equation, and then use the fact that q+r=c.
b) Add the left sides and the right sides of each equation, and then use the fact that q=c2 and r=c2.
c) Multiply the left sides and the right sides of each equation, and then use the fact that q⋅r=1.
d) Multiply the left sides and the right sides of each equation, and then use the fact that q+r=c.
