Match the columns with appropriate optimization that can be applied to the left column.
Column - I Column - II
I. a = b + 0 a. Constant folding
II. a = b * 32 b. Strength Reduction
III.PI = 3.142; x = PI/2 c. Code Movement
IV. for(i = 0; i < 10; i++) d. Algebraic Simplification
a = b * c; e. Constant propagation
