B Correct answer
Explanation

Using the Pythagorean theorem, hypotenuse = sqrt(6^2 + 8^2) = sqrt(36 + 64) = sqrt(100) = 10 cm.

AI explanation

Using Pythagoras theorem, the square of the hypotenuse equals the sum of the squares of the base and the perpendicular. The square of the hypotenuse is 6 squared plus 8 squared, which is 36 plus 64, giving 100. Taking the square root of 100 gives the length of the hypotenuse as 10 cm.
