Quizplus · Accepted Answer

The wear-and-tear theory suggests that aging is due to the accumulation of damage to the body over time and the body's decreased ability to repair this damage. It is not a programmed theory of aging (option A) or the same as the immunological theory (option B), which suggests that aging is due to the decline of the immune system. While environmental toxins and damage to DNA may contribute to the wear-and-tear effect, they are not the core of the theory (option D).
