Is number '0' considered to be a multiple of other numbers?

for example, the following quesiton appeared in a kaplan practice test:

if x is a prime number, what is the value of x.

1. x< 15
2. (x-2) is a multiple of 5

In this case, i chose C cause 1 would give you 2,3,5,7,11,13 and 2 would give 7,17, 37 etc

choosing c would give 7. however, the kaplan explanation also includes 2 as the prime number cause 2-2 is 0 and hence is a multiple.

Can someone please explain whether we consider 0 as multiples?

thanks

I think that a "multiple" could be any INTEGER.
0 is an Integer, so.. Kaplan is correct.
