Which of the following numbers has a zero in its units digit?
I. (4!)×(4!)×(3!)×(11)×(17)×(31)
II. (2!)×(3!)×(3!)×(5)×(17)×(31)
III. (2!)^5×(3!)^5×(4!)^5  Select the correct option:	A) I only	B) II only	C) III only	D) I, II and III	E) II and III
At a glance solution   0 in the units place will come only when you have at least a multiple of 2 and 5   Check clearly none of the given option is both a multiple of 2 and 5 except option (II)   Hence (II only) is the correct answer.
