Potential energy is involved in each of these events. match each event with it's source of potential energy.

Trampolin --> elastic potential energy

Elastic potential energy is the form of energy stored in an elastic object, such that the trampoline.

Chemical substance --> chemical potential energy

Chemical potential energy is the form of energy stored in the chemical bonds of the molecules, and it is released when the substance reacts and releases heat.

The skydiver --> gravitational potential energy

Gravitational potential energy is the form of energy possessed by an object located at a certain height above the ground - in this case, the skydiver, which is at a very high altitude above the ground.

The correct answer is option C, a worm

Explanation:

Schistosomiasis is a disease caused by parasitic worms. The common causing agents are Schistosoma mansoni, S. haematobium, and S. japonicum , S. mekongi and S. intercalatum . An individual gets infected when they come in contact with contaminated freshwater. People urinating or defecating in the water causes contamination of freshwater. The parasitic worm develop and multiply inside the snails. The parasite then leaves the snail and enters the water where it can easily penetrate into an individual's body (who are wading, swimming, bathing, or washing in contaminated water) through their skin.
