If x is a whole number, then x²(x² - 1) is always divisible by	Choose one:
A) 12-x  B) Multiple of 12  C) 12  D) 24  E) 48
Putting x = 2,we get 2²(2² - 1) = 12.   checking with other integers, the above equation always gives a value which is a multiple of 12,   So, x²(x² - 1) is always divisible by 12.   ANSWER:12
