Answer: Option C

Explanation:

1. Addition of odd and even integers yields odd intgers. Example: 4 + 3 = 7. So, statement 1 is true.

2. Multiplication of odd and even integers yields even integers. Example: 4x3 = 12. So, statement 2 is false.

3. 2x is even and y is also even. So, 2x + y is even. Therefore, statement 3 is true.
