The correct option is B Intra specific competition
Competition is a rivalry for obtaining the same resource. Competition is of two types of intraspecific (competition amongst members of same species) and interspecific (competition amongst members of different species). An intra specific competition will be more severe as competing organisms will have same or identical requirements. Thus, a high density of elephant population or high density of organisms of any one particular species in an area will lead to intraspecific competition as the elephants will compete for the same resources available in the area.
