Answer: The correct answer would be biotic, intraspecific competition.
Step-by-step explanation:
Biotic refers to the living component of an ecosystem whereas abiotic refers to non-living components such as air, water, soil, et cetera.
Interspecific means between two species whereas intraspecific means within a species.
Thus, intraspecific competition is a type of ecological interaction in which members of same species compete for same resources such as food, mate, et cetera.
Mutualism is a type of interaction in which both the organisms are benefited from each other. for example, bees and flowering plants.
Thus, the correct answer would be biotic, intraspecific competition.
