all the roots of x(x+1)(x+2)......(x+n) where n is a natural no are:a)b)>1/n!c)d)none

Option a and c are not seen here.

x=0 itself is a root of this expression. and if we take x= -n then x+n=0 and so -n will be a root. if n=1 then -1(-n) is definitely  not greater than 1(1/n). there fore option b is also wrong. so i feel that this question is incoplete and with the available information i can say that it is none.
