The correct answer is option D, that is, phenotypic.
The composite of an organism's observable traits or features, like its development, morphology, physiological or biochemical characteristics, products, and behaviors of an organism is known as a phenotype.
A phenotype is an outcome of the expression of the genetic code of an organism, its genotype, and the effect of environmental elements and the associations between both. The error in transcription or translation process usually leads to physical or phenotypic modifications in an organism.
