Correct option is C
An ecotype is a population (or subspecies or race) of an organism that is adapted to local environmental conditions. These adaptations may be genetic or phenotypic changes that allow the organism to thrive in specific environments.
Ecotypes are a result of natural selection where certain traits are favored in specific environmental conditions, leading to adaptations in the population.
Ecotypic variations can be seen in plants and animals that exhibit different forms or behaviors depending on the environment they are in.
Over time, ecotypes may evolve into distinct species if isolation and different selective pressures continue.
