Dear Diyanasha Seth,

The solution for the given query is as follows:-

Magnetic energy is odd one out here out of light energy, heat energy and sound energy.

And, for this the reason is:-

We can touch magnets but we can't touch light, heat and sound. We can just feel them.

So the answer is Magnetic Energy.

Hope this helped. Feel free to drop your queries related to this or else.

Good Luck :)
