d.) Oxygen is a biotic factor, because it is required for life and found in all living things.

An environment's biology includes both non-living, abiotic factors like atmosphere, water, soil, sunlight and temperature; and biotic factors which are living components of the ecosystem like plants, fungi, bacteria and animals. These factors interact within a community, and lead to a gradual change of an ecosystem over time.
