A
Abiotic Factors
B
Limiting Factors
C
Biotic Factors
D
None of the above
Explanation: 

Detailed explanation-1: -A limiting factor is anything that constrains a population’s size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources.

Detailed explanation-2: -Environmental factors such as rainfall, climate, predators, shelter and food availability can change. Often, these factors play an important role in the survival of populations.

Detailed explanation-3: -A key factor is defined as the factor in the activities of an undertaking which, at a particular point of time or over a period, will limit the volume of output. Other variant terms are limiting factor, Principal Budget Factor & scarce factor.

Detailed explanation-4: -In general, we define density-dependent limiting factors as factors that affect the per capita growth rate of a population differently depending on how dense the population already is. Most density-dependent factors make the per capita growth rate go down as the population increases.

Detailed explanation-5: -Density-dependent limiting factors make the per capita growth rate decrease as the population increases. Density-dependent limiting factors tend to be biotic, including factors such as food and disease.
