Answer:
Explanation:
By definition, after a radio active decay, a parent isotope will create a daughter isotope.
Layer C is exactly one half-life from Layer E at 50000 years. So half of the original parent isotopes from Layer E would have decayed to form daughter isotopes. As C has 18 radioactive isotopes together, E should have 6 daughter and 6 parent isotopes.
