A Correct answer
Explanation

For a right triangle, inradius r = (a + b - c) / 2. Here, r = (3 + 4 - 5) / 2 = 2 / 2 = 1.

AI explanation

Using the formula for the inradius of a right triangle, r equals the sum of the legs minus the hypotenuse all divided by 2. Substituting the given values, we get r equals (3 + 4 - 5) divided by 2. This simplifies to 2 divided by 2, which results in an inradius of 1.
