C. 6,8,10

Explanation:

Pythagorean triples are sets of three sides of a triangle (leg, leg, hypotenuse) that are natural numbers, like 3, 4, and 5.

3^2 + 4^2 = 5^2, so it's a triple.

6,8,10 is a triple because it can be simplified to 3,4,5 by dividing each term by 2; it's similar to the 3,4,5, so it's a triple.
