C Correct answer
Explanation

In a right-angled triangle, the length of the median to the hypotenuse is half the length of the hypotenuse. BM = AC / 2 = 10 / 2 = 5.

AI explanation

Apply the property of a right-angled triangle that the median drawn to the hypotenuse is exactly half the length of the hypotenuse. Given that AC is the hypotenuse measuring 10, the median BM is calculated as half of 10. Therefore, the length of BM is 5.
