- A Uncontrolled cancer cell growth and division
- B Normal cellular aging and senescence
- C Faster DNA replication during early development
- D Chromosome condensation before cell division
Correct answer: B. Normal cellular aging and senescence
Explanation: Telomeres shorten with each cell division. When critically short, cells enter senescence or apoptosis. This contributes to aging.
