• When two related species fight for limited resources, there is a competition between the species. These types of interactions are called competition. Lions and leopards exhibit competition.

• Commensalism is a type of integration, one species population benefits from the other species population. But the other species population does not benefit nor is it harmed in any way. Commensalism is shown by Cattle egret and cattle.

• Mutualism is the positive interaction in which two organisms live close together and benefit each other equally. Lichens are a classic example of mutualism in between fungi and algae.

• Parasitism an interaction of populations where a parasitic mode of nutrition is clearly seen, with one species being completely dependent on the other host species for all its meals/ nutrient requirements. Parasitism is exhibited by tapeworm and man. So, option A is correct match.
