Explanation
Francis, Kaplan, and propeller turbines are all categorized as reaction turbines because they operate based on the pressure difference across the blades, converting pressure energy into mechanical energy. In contrast, impulse turbines rely solely on the velocity of water jets. Therefore, option B is correct.
