Answer: the correct answer is B) Phenotype.
Phenotype corresponds to a characteristic/ trait or morphological form of a living organism.
For instance, in this case, texture of pea coat is a particular characteristic of the pea. This can be smooth or wrinkled. Smooth pea coat therefore indicates a phenotype of the garden pea.
On the other hand, genotype refers to the genetic makeup of the organism. Chromosomes are the thread like structures that are composed of DNA ( deoxyribonucleic acid, which is the genetic material of living organisms).
