Answer:
B. 6,8,10
Explanation:
to find a right triangle the equation: a^2 + b^2 = c^2, so just plug each number in to see.
6^2 + 8^2 = !0^2
36 + 64 = 100
100 = 100
Personally i knew almost immediately because 3,4,5 are the most common right triangles example and 6,8,10 are just a x2 of them so yea.
