Detailed explanation-1: -The correct answer is (c) analogous structures. Analogous structures are defined as traits or structures that are similar in two different species, but were not inherited from a common evolutionary ancestor. That is, the structures evolved independently but are similar because of shared selective pressures.
Detailed explanation-2: -Convergent evolution occurs when species occupy similar ecological niches and adapt in similar ways in response to similar selective pressures.
Detailed explanation-3: -Divergent evolution occurs when a subgroup of a species evolves traits different from its ancestors. The trait usually sprung from selective pressures. Such pressures drive natural selection and compel organisms to evolve.
Detailed explanation-4: -Analogous structures are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature (compare to homologous structures) and which evolved in response to a similar environmental challenge.
