C
speciation
D
None of the above
Explanation: 

Detailed explanation-1: -adaptation: Any heritable characteristic of an organism that improves its ability to survive and reproduce in its environment.

Detailed explanation-2: -Phenotypic adaptation involves changes in the body of an organism in response to genetic mutation or certain environmental changes. These responsive adjustments occur in an organism in order to cope with environmental conditions present in their natural habitats.

Detailed explanation-3: -Local adaptation involves genetic differentiation specific to each environment, whereas phenotypic plasticity allows single genotypes to express different phenotypes under diverse environmental conditions.

Detailed explanation-4: -Phenotypic adaptation is the change in the appearance of organisms due to genetic mutation or in response to the surrounding environment. Example: desert plants possess sunken stomata on the leaf to prevent water loss.
