A species' fundamental niche is the full range of climate conditions and food resources that permit the individuals in a species to live. This is in contrast to the realized niche, which is the actual range of conditions and resources where the species is found due to interactions with other species and other limiting factors. The ecological niche refers to the role and position of a species within its ecosystem, which includes both the fundamental and realized niches. Therefore, while choices A, C, and E all include aspects of a species' niche, only choice B specifically refers to the fundamental niche.
