Why are certain traits adaptations in one environment, but not in another?

The correct answer will be option-B

Explanation:

Adaptation is a process by which the species changes itself to become best fitted to their environment. The adaptation is the result of the genetic changes that are passed on from the parents to the offspring and become established in a population. The natural adaptation is the driving force of the evolution of organisms on earth.

Since adaptation ensures the survival of the species to their respective environment which increases their reproductive rate, therefore, Option-B is the correct answer.
