Which information helps scientists determine the survival probability of a population?

A. the level of genetic variation in the population
B. the feeding habits of an individual in the population
C. the existence of natural selection in the population
D. the number of offspring of an individual in the population

A. the level of genetic variation in the population

This information is crucial for scientists to determine the survival probability of a population as genetic variation allows a population to adapt to changing environmental conditions and increase its chances of survival.
