Explanation:

In genetics, the phenotype is the observable physical or biochemical characteristics of an organism. It is determined by the interaction of its genotype (genes and alleles) with the environment. Option A refers to genotype (genes), Option C refers to alleles (part of genotype). Option D wrongly combines phenotype (physical appearance) with alleles (genotype component). Only Option B correctly defines phenotype as the physical appearance of an individual.

Answer:

B. the physical appearance of an individual
