The correct answer is D. Both A and C
Explanation:
In biology, a phenotype refers to a trait or characteristic that is observable in an organism, including physical characteristics, physiological characteristics, and behavioral characteristics. The phenotype is the result of the expression of genes or environmental factors. Considering this, both "a certain duck has a blue beak" and "most cheetahs live solitary lives" are phenotypes because they are traits that can be observed in terms of morphology or physical characteristics in the case of the duck or in terms of behavior in the case of the cheetah. On the other hand, a mutation is not necessarily a phenotype except if it is expressed.
