to form the right triangle you need a perfect square which only A will give you
6^2 +8^2=10^2
36+64=100
4^2+5^2 does not equal 7^2 or 49 but sqrt of 41
5^2+7^2 does not equal 11^2 25+49 =74 sqrt of 74
4^2 +9^2 does not equal to 12^2 but 16+81=97 sqrt of 97

The corrext answer is (a). The formula is: The sum of the squares of the sides equals the square of the hypotenuse.
Thus: 6 squared = 36
8 squared = 84
36 + 84 = 100
The square root of 100 is 10
