Statement A: Reproduction ensures the continuity of species generation after generation
Statement B: Life spans of organisms are not necessarily correlated with their sizes

detailed solution

Correct option is C

Life spans of organisms are not necessarily correlated with their sizes; the sizes of crows (15 years) and parrots (140 years) are not very different yet their life spans show a wide difference.Reproduction is defined as a biological process in which an organism gives rise to young ones (offspring) like itself. The offspring grow, mature and in turn produce new offspring. Thus, there is a cycle of birth, growth, and death. Reproduction thus enables the continuity of the species, generation after generation.
