Answer:
B. Artificial selection created a larger breed of chicken.
Explanation:
The average size of a grocery store chicken has more than doubled in the past century. The most likely reason for this change is that artificial selection created a larger breed of chicken.
Artificial selection, also known as selective breeding can be defined as the process of identifying desirable traits in living organisms such as animals and plants, and selectively taking steps to ensure that those phenotypic traits are perpetuated in the offsprings or future generations.
This ultimately implies that, farmers or breeders are saddled with the responsibility of choosing which plant or animal are selected for the production of favorable (special) offsprings.
