Answer 2

The statement "2 is a rational number and it is the only even prime number." will always be true.

Explanation:

Rational numbers are the numbers which can be expressed in the form of $\frac{p}{q}$ where q≠0.

Here, 2 is a rational number because 2 can be expressed as $\frac{2}{1}$ , in which q≠0. Hence, 2 will always be a rational number.

Prime numbers are the numbers which have only two factors i.e. 1 and itself.

Example - 1,2,3,5,7,11,13 etc.

2 is the only one number which is even prime number because all other even numbers have more than 2 factors, but 2 is the only even number which have only 2 factor.
