Best answer
The correct option is (c) Valves and bends

Easiest explanation: Minor losses play an important role in calculating the flow, pressure and energy of the piping system. Fluid that moves through the pipe carries momentum and energy due to the forces acting on them. Thus, these minor loses are developed due to valves, pipe diameter and bending.
