Which of the following must be divisible by 4, given that y is a positive integer? Pick:
A) (y−1)*y*(y+3) B) y^2*(y−3) C) y(y^2−2) D) y(y+2)^3 E) (y−2)·(y+1)·(y+3)
option A) (y−1)*y*(y+3)- assume y any positive integer e.g 5, plug it into the various options and check if the result . hence answer should be (y−1)*y*(y+3)
