The correct answer is B. Geronotology.
Gerontology is the study of the process of aging. It is a multidisciplinary field that includes biology, psychology, sociology, and medicine. Gerontologists study the physical, mental, and social changes that occur as people age. They also study the factors that influence aging, such as genetics, environment, and lifestyle.
Genocology is the study of the evolution of genes. It is a branch of genetics that focuses on the changes in gene frequencies in populations over time. Genocologists study the factors that influence genetic change, such as mutation, natural selection, and gene flow.
Ontogeny is the study of the development of an individual organism from conception to death. It is a branch of biology that focuses on the changes that occur in an organism’s structure, function, and behavior as it grows and develops. Ontogeny is often studied in conjunction with phylogeny, the study of the evolutionary history of a group of organisms.
None of these options is the study of the process of aging.
