The Correct Option is A

Solution and Explanation

Dominance occurs when one allele masks the other in a heterozygote (a-ii). Codominance is when both alleles are expressed fully in a heterozygote (b-iii). Pleiotropy refers to one gene affecting multiple traits (c-iv). Polygenic inheritance involves multiple genes influencing a single trait (d-i).
