With the of an example explain the law of conservation of energy

The law of conservation of energy states that energy can neither be created nor be destroyed, but it can be transformed from one form to another.

So I considered an example of it as follows: water is stored at height with potential energy, the water flows and its potential energy is converted into kinetic energy. It flows to rotate a turbine with mechanical energy. Then the kinetic energy is converted into electrical energy. In our house the electrical energy is converted into luminous energy, heat energy, and so on.

explanation:

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.
