Explanation:
Density-dependent factors are biological factors adopted by the population as a resource. The things can be like shelter, food, or different poor resources. Density-dependent factors affect fitful variations in the population as its density fluctuations. If the population is small, these portions typically support improved rates of birth and lower will be the death rates, empowering the population to increase and when the population is big and thick, these factors display that the birth rate is decreased and death rate became higher.
So option B (hybrids have lower fitness than either parent population) is the correct answer.
