Answer:
The correct answer would be option d.
Resources such as solar energy, wind energy, tidal energy, et cetera are renewable resources. Thus, they are inexhaustible in nature. In addition, they are a clean source of energy, that is, they do not cause pollution or environmental changes.
In contrast, fossil fuels such as petrol, diesel, et cetera are non-renewable resources, that is, they are present in limited amount in nature. They would exhaust in the near future if they are being used on the current pace.
In addition, they also cause pollution and global changes such as global warming, climate changes, et cetera.
