Concept:Non-renewable sources are those that exist in limited supply and cannot be replaced quickly.
Renewable sources are those that are naturally replenished, like sunlight and wind.
Explanation:Coal is a fossil fuel formed over millions of years.
Its supply is limited, so coal is a non-renewable source.
Uranium-236 (
U-236) is used as nuclear fuel.
It is also available in limited quantities and is non-renewable.
Solar energy comes from the Sun and is continuously available.
Wind energy is produced by air movement and is naturally replenished.
Therefore, solar and wind are renewable sources.
So, the non-renewable sources among the given options are coal and Uranium-236.
That matches I and IV only.
Answer:C. I and IV only.
