Answer: (A)

Biological changes that happen as time passes and influence the body's structure and functioning describe the aging process. It directly addresses getting older and the gradual, natural changes in tissues and organs—like slower metabolism, changes in skin, bones, vision, and organ function—that are central to CNA care as residents age. Activities of daily living are the tasks people perform each day, not the biological changes themselves. Adaptive equipment refers to tools that help people perform tasks, not the aging process.
