The distribution of a species depends on several factors, and these factors would be more or less important depending on the species, for example, the requirements of a plant would be different than the ones of an animal.
These factors can be classified as biotic or abiotic.
Biotic factors are the ones that depend on other living beings, from the same or different species, some of them are:
-Predation
-Competition for food or other resources.
-Availability of preys
Abiotic factors, on the other hand, are not determined by living beings, but rather by chemical and physical things, these include:
-Clime: Sunlight, humidity, temperature, precipitation, etc.
-The characteristics of the soil: Coarseness, pH, aeration, etc.
-Water availability.
-Wind exposure
In this question, while all the options are factors that determine species distribution, not all of them are abiotic. Soil pH, wind exposure, and solar radiation are physical and chemical factors, so they are abiotic; on the other hand, competition for food involves other living beings, so this is a biotic factor.
