Resource partitioning would be most likely to occur between:.
a) sympatric populations of a predator and its prey.
b) sympatric populations of species with similar ecological niches.
c) sympatric populations of a flowering plant and its specialized insect pollinator.
d) allopatric populations of the same animal species.
e) allopatric populations of species with similar ecological niches.

Explanation:

Resource partitioning;  is the way of  division of resources  by species with similar ecological niche to  avoid competition in an ecological niche which help in reduce competition,  through which species  with similar ecological niche  can coexist. In any environment, organisms compete for limited resources, like food,  so organisms and different species have to find ways to participate  timing of taking food or area to coexist with one another known as resource partitioning, to get rid off from resource problem.
