Let p: The number is even.
Let q: The number is prime. 

1)  = The number is even and prime is not possible always Because 2 is the only even prime number.

2) = The number is even or prime is not possible always Because 2 is the only even prime number and also the even number to the power prime does not always prime.

4) =The number is prime if the number is even is not possible always.

3) = The number is even if the number is prime because any number multiplied by an even number is always even. This is the correct answer.
