If the product of two whole numbers is zero, can we say that one or both of them will be zero? Justify through examples.

Yes, if we multiply any number with zero the resultant product will be zero.
Example: 2 x 0 = 0, 5 x 0 = 0, 9 x 0 = 0
If both numbers are zero, then the result also be zero.
0 x 0 = 0
