Hydrophobic substances such as vegetable oil are nonpolar substances that repel water molecules.
What are non polar substances?Nonpolar substances are molecules that do not have a charge separation between different parts of the molecule. This means that they do not have a polar, or electrically charged, end, and as a result, they do not dissolve well in polar solvents like water.
Nonpolar substances are hydrophobic, meaning that they repel water molecules, and tend to dissolve in other nonpolar substances, such as oils and fats. Examples of nonpolar substances include hydrocarbons like gasoline, fats, oils, and waxes, as well as some gases, like nitrogen and methane. Nonpolar substances play an important role in a variety of biological and industrial processes, and their unique properties make them useful for many different applications.

What are Renewable and Non-Renewable resources?Resources are divided as renewable or non-renewable. A renewable resource can renew itself at the rate it is used, while a non-renewable resource has a limited supply. Examples of renewable resources are timber, wind and solar while non-renewable resources are coal and natural gas.
Renewable energy is the energy which can be used repeatedly and it is renewed again after a short period of time which is defined as the type of energy resources that can be renewed naturally. Renewable sources of energy can replace the conventional sources of energy which produce harmful gases which are harmful as well as costly.
Non-renewable resources are those which cannot be reused or reproduced, it is used only once and takes a long time to reproduce. These are also not good for the environment. Burning fossil fuels harms our environment.
Thus, Solar Energy would best be categorized as inexhaustible. So, the correct option is (C).
