How can specific phenotypes within a population lead to adaptation?

A; decrease probability of survival and decrease adaptation.
b: Survival unaffected by phenotypes within a population.
c: Increase probability of survival and adaptation.
d: No effect on survival and adaptation.

c: Increase probability of survival and adaptation.

Specific phenotypes within a population can lead to adaptation by increasing the chances of survival in a particular environment. For example, if a certain phenotype allows an organism to better camouflage itself from predators, it is more likely to survive and reproduce, passing on that advantageous trait to future generations. Over time, this can lead to the adaptation of the entire population to better suit its environment.
