Carbon-14 is useful to estimate the date of fossils that are less than 50,000 years old.

Option C

Explanation:

Carbon-14 is the best option to use by estimating the date of fossils that are below 50,000 years old. This is because the carbon-14' half-life is around 5730 years i.e. the existing Carbon-14 in the living bodies decays in 5730 years once they die.

That's the reason Carbon dating utilized to estimate the age of objects that are below 50,000 years old. Objects such as dead plants, wood or human artifacts that are younger than 50,000 years.

After the death of living beings, Carbon 12 and Carbon 14 existing in these organisms starts decaying by converting into Nitrogen. By estimating the leftover amount of carbon 14 in their bodies, scientists can evaluate their age.
