B)cellular clock theory
C)activity theory
D)free radical theory

The cellular clock theory suggests that aging is a result of the limited number of times that cells can reproduce, due to the shortening of telomeres (the protective ends of chromosomes) with each division. This eventually leads to cellular senescence and an inability to repair damage, ultimately contributing to the aging process. The wear-and-tear theory suggests that aging results from accumulated damage to the body over time, while the free radical theory posits that aging is caused by the accumulation of reactive byproducts of metabolism that damage cells. The activity theory, on the other hand, suggests that a positive attitude towards aging and continued engagement in life activities can promote healthy aging.
