Explanation:

Genes are segments of DNA. They carry the code for making proteins. A gene is not a unit of protein (a is incorrect). Amino - acids are the building blocks of proteins and genes code for proteins not directly for amino - acids (c is incorrect). A gene is a unit of DNA that contains code for the creation of one or more proteins. Option b is the most accurate among the given options.

Answer:

b. A gene is a unit of DNA that contains code for the creation of one protein.
