B Correct answer
Explanation

In genetics, knocking out a gene implies that particular gene would not be expressed. Altering the genotype of an individual normally alters the phenotype. For example, if you knocked out a particular gene and found out that the resulting fly has underdeveloped wings compared to the wild-type, it could suggest the gene has a role in embryonic wing development.
