Answer 2

Answer:

The energy source which is exhaustible is geothermal energy i.e.option(D).

Explanation:

First, let's understand what is the exhaustible energy source.

These are those resources that are present in limited quantity or take many years to replenish and can be used up by human activities. Examples are coal, petroleum, etc.

Now let's categorize the options one by one.

(A) Tidal energy- energy produced by the water tides. These are inexhaustible.

(B)Wind energy- energy produced by the winds. The main equipment which produces this energy is windmills. These are inexhaustible.

(C)Solar energy- energy produced by the sun. The main equipment used is solar plates. These are inexhaustible.

(D)Geothermal energy- the energy produced by the heat within the earth. The heat within the earth comes from coal and petroleum present within the earth. These are exhaustible.

Hence, the correct answer among the given option is Geothermal energy i.e.option(D).
