Solution
The correct option is C B. L. Strehler
Bernard Louis Strehler defined aging by means of four postulates:
a. Aging is universal: a phenomenon associated with aging must occur in different degrees in all individual of the species.
b. Aging must be intrinsic: the causes that are the origin of aging must be endogenous.
c. Aging must be progressive: changes that lead to aging must occur progressively throughout the lifespan.
d. Aging must be deleterious: i.e., a phenomenon associated with aging will only be considered as part of aging process if it is 'bad' for the individual.
Thus, the correct answer is option (C).
