On your quest to discover early hominins in africa, you find some geologic strata with fossils that resemble early hominins. you would like to know when these hominins lived; of the following, which would be the best way to proceed with finding an age for these fossils?

A.

Explanation:

Based on the information provided within the question it can be said that the best option in this scenario for finding the age of these fossils would be to collect a sample of the volcanic ash layers above and below the fossil layer and date the volcanic deposits with Argon dating methods. Such a method would be Potassium-Argon dating in which the product of the radioactive decay of an isotope of potassium (K) into argon (Ar) are compared in order to calculate an estimated age.
