If Sara believes that aging is the result of chromosome breakage that occurs each time a cell divides and accumulates until the cell no longer can reproduce itself, her view is most similar to:
A) free radical theory
B) a stochastic theory of aging
C) a biological clock theory of aging
D) the theory of senility

Sara's belief about aging is most similar to the theory of biological clock. Both propose that aging is a result of a gradual accumulation of damage to the genetic material in cells. However, the biological clock theory is more specific in suggesting that a predetermined lifespan is determined by an internal genetic clock in the body rather than cell division alone. The free radical theory and stochastic theory both propose that aging is a result of damage to cells caused by external factors or random events, while the theory of senility is a narrow proposal that aging is solely a result of changes in the brain.
