Best answer
Right option is (a) energy to velocity and pressure

For explanation: The efficiency of the pump is the ratio of the energy supplied by the motor to the increase in velocity and pressure energy given to the fluid. Propellers pumps and centrifugal pumps have high efficiency. Jet pumps and airlift pumps are less efficiency.
