B. Overproduction

Explanation:

Overproduction is one of the main part of natural selection whereby an organism reproduces more offspring, of which only a few would be able to survive given the environmental condition amd factors that would be against the survival of the offspring to maturity.

From Ronald observation, we can see that the bird produces more eggs than would survive. Only 3 of the chicks survived.
