Answer
Cellular aging suggests that aging is inevitable because eventually the telomere is gone and cell duplication ceases.
Explanation
The concept of cellular aging indicates that as time progresses, due to repeated cellular duplication, telomeres present at the ends of chromosomes in a cell become gradually shortened. Telomeres are important in protecting the chromosome from deterioration and ensure accurate DNA replication. When these telomeres are gone or shrink to a critical length, the DNA is exposed to damaging risks and the cell may enter a state of senescence - ceasing further duplication or leads to cell death. The potential induction of errors in DNA over time also can contribute to the inevitable aging process. However, the statements about lengthening of telomeres or toxin levels reducing telomere production do not align entirely with the well-supported views on cellular ageing. Cellular ageing, based on current knowledge, considers telomere shortening and damage accumulation in DNA as causes, thus the option "eventually the telomere is gone and cell duplication ceases" rightly reflects this.
