D
artificial selection
Explanation: 

Detailed explanation-1: -Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

Detailed explanation-2: -An example of artificial selection-Dog breeding Domestication is the act of separating a small group of organisms (wolves, in this case) from the main population, and select for their desired traits through breeding.

Detailed explanation-3: -Artificial selection is an evolutionary process in which humans consciously select for or against particular features in organisms – for example, by choosing which individuals to save seeds from or breed from one generation to the next. People have been artificially selecting plants and animals for thousands of years.

Detailed explanation-4: -Selective breeding is also known as artificial selection. Artificial selection is driven by human intervention.

Detailed explanation-5: -A common example of artificial selection in animals is dog breeding. As with racehorses, particular traits are desirable in different breeds of dogs that compete in dog shows. The judges look at coat coloring and patterns, behavior, and even teeth.
