Best answer
The correct choice is (a) Containing single type of organism

Best explanation: In biology, axenic describes the state of a culture in which only a single species, variety, or strain of organism is present and entirely free of all other contaminating organisms. Axenic culture is also an important tool for the study of symbiotic and parasitic organisms in a controlled manner.
