The scientific study of aging is called?

• A. Crystallized intelligence
• B. Gerontology
• C. Fluid intelligence
• D. Great-grandparenthood

Answer: (B)

Gerontology is the study of aging. It’s the interdisciplinary field that examines how people age biologically, psychologically, and socially, as well as the implications for healthcare, policy, and society. This term specifically names the science and study of aging processes and their impact on individuals and populations.

Crystallized intelligence and fluid intelligence are concepts in cognitive psychology describing types of intelligence, not a field that studies aging itself. Great-grandparenthood refers to a family relationship, not a scientific discipline.
