Given the positive integer x, which of the following must be divisible by 3?
Choose the correct option
A) x(x^2−2)	B) (x−1)*x*(x+1)	C) x(x+2)^3	D) x^2*(x−5)	E) x^2*(x−5)
option B) (x−1)*x*(x+1) which represents the product of three consecutive integers, which will always be divisible by 3. hence answer should be (x−1)*x*(x+1)
<result>B</result>
