Question: Is a + b = Odd?
Statement 1:The product of the integers is odd.
Since we are dealing with integers and their product is odd
i.e. both the integers must be Odd hence the sum must be even
Case 1: a = 3 and b = 3, a*b = Odd and a+b = 0 (even)
Case 2: a = 3 and b = -3, a*b = Odd but a+b = 0 (even)
SUFFICIENT
Statement 2: At least one of the integers is odd.
Case 1: a = 3 and b = 3, but a+b ≠ Odd
Case 2: a = 1 and b = 2, but a+b = Odd
NOT SUFFICIENT
Answer: Option A

Is question stem Correct? Is it if or is ?
Certain pair of integers would be 2 or even count of integers ??
Assuming it's is
#1
The product of the integers is odd.
Set would have all integers odd and since it's asking for a pair(2 count) so sum would be even
Sufficient
#2
At least one of the integers is odd
Pair can be e,o or o,o
Sum is odd or even
Option A is correct
