B Correct answer
Explanation

The curved surface area of a cylinder is the circumference of the base multiplied by the height, which is 2 * pi * r * h.

AI explanation

The curved surface area of a cylinder is determined by multiplying the base circumference by the height. Since the circumference of the base is 2 pi r, the formula for the curved surface area is 2 pi r h.
