Ahmad uses an electric pump to raise water to a reservoir on his farm. The pump is very noisy, and Ahmad’s uncle, who is an engineer, told him that only 50\%50%50, percent of the energy it consumes is delivered as gravitational potential energy to the water. When Ahmad turns off the pump, he notices that when he touches it, it has not warmed up. What happened to the electrical energy provided to the pump?

a : It mostly transformed into gravitational potential energy, and a small portion transformed into sound.
b : It mostly transformed into sound, and a small portion transformed into gravitational potential energy.
c : It transformed into gravitational potential energy and into sound in equal portions.
d : It mostly transformed into sound energy and gravitational potential energy, and a small portion disappeared.
