Answer:
I can't give you the answer because i dont have anything to choose from but i can explain natural selection.
Step-by-step explanation:
"The fittest organisms in a population are those that are strongest, healthiest, fastest, and/or largest. Natural selection is about survival of the very fittest individuals in a population." If there are weaker members in a population, they have less of a chance of survival, therefore, undesirable traits will be eliminated in time.
hope this helps!
