Let the first number is 2n, then the next number is 2n+1
We can see one of the two consecutive integers must be an even number.
Then, product of them gives the following expression
2n\cdot(2n+1) = 2n(2n+1)
which shows the product the two numbers is an even number, hence divisible by 2
A is the right choice
