Direction: Read the following Caselet DI carefully and answer the following questions. 3 cubes P, Q, and R are cut from the cubes A, B, and C respectively.
The length of the side of cube P is given by the equation x - 12x + 36 = 0 and the length of the side of cube A is 2 cm more than cube P.
The length of the side of cube Q is given by the equation y + 21y - 46 = 0 and the length of the side of cube B is 3 cm more than cube Q.
The length of the side of cube R is given by the equation z - 10z + 25 = 0 and the length of the side of cube C is 4 cm more than cube R.
Here x, y, and z are in centimeter.
From the given cubes, which two cubes have equal side length?

Options

A. R and A
B. P and C
C. R and B
D. R and P
