we can apply some logic to get answer to this question.

If the product of two integer is 40 we can be sure that both the two integers are either -ve or +ve

Hence the ans should be a summation of two +ve integer or summation of two -ve integer

Looking at the answer choices option C becomes a probable candidate for our answer

This is because 3 is a +ve number we know for sure a +ve ans choice in this question can come from summation of two positive number only

There are only two possibilities to get a summation of 3 by adding two numbers i.e. \(2\) and \(1\) or \(3\) and \(0\)

The pair of \((3,0)\) is a not a possibility as \(0\)*something = \(0\)

and \(2\) and \(1\) multiply to \(2\) so our answer is C
