Radiation has caused a mutation in the DNA of a bird. This change will most likely be passed on to its offspring if the mutation occurs in its A. Sperm cell
B. Feather cell
C. Skin cell
D. Nerve cell

A. Sperm cell

Explanation:

Mutations are genetic alterations in the nucleotide sequence that form the genome of a given organism. In general, mutations have negative effects (i.e., mutations are generally deleterious), but sometimes these genetic changes may be adaptive (and therefore beneficial). Somatic mutations are genetic alterations acquired by somatic cells (they can not be inherited by the offspring), while germline mutations occur in gametes (sperm and egg) and they can be inherited by the offspring, thereby affecting the progeny of the organism.

b is the best answer for this question.
