Its D

zero is not divisible by any number. When zero is divided by any number then quotient is 0 and remainder is that number.

should be D ... regarding negative numbers ... just think of any -ive no x if x+1 is divisible by 7 then x cannot be divisible by 7 ..... there has to be a gap of 7 to be divisible
