Given x and y are consecutive integers i.e y = x+2

Statement 1: since the product of the 2 numbers is negative, we can say that one of them is positive and the other one is negative.
Since these numbers are consecutive, they have to be -1 and +1. Therefore, their sum should be 0. Sufficient.

Statement 2: One of the integers is equal to –1.
The other number could be -3 or +1. Therefore, the sum could be either -4 or 0. Clearly insufficient.

Hence A) should be the answer.

(1) The product of x and y is negative --> only possible if the pair is -1 and 1, sum is 0.....sufficient
(2) One of the integers is equal to –1 --> we can have -3 & -1 or -1 & 1, hence sum can be -4 or 0......insufficient

Ans. A)
