Official Solution:

What is the remainder when a positive integer $$p$$ is divided by 2?

Notice that a positive integer can yield only two remainders upon division by 2: 0 (when the dividend is even) and 1 (when the dividend is odd). So, we are basically asked whether $$p$$ is even or odd.

(1) $$p$$ is a prime integer. $$p$$ could be 2, so even, as well as 3 (for example), so odd. Not sufficient.

(2) $$p \gt 10$$. Clearly insufficient.

(1)+(2) Any prime number greater than 10 is odd and thus leaves the remainder of 1 when divided by 2. Sufficient.

I believe that correct statement is:
Any prime number greater than 10
