Answer and Explanation:
In a cell, the smaller the surface area in relation to its volume, the lower the rate of diffusion. The ratio of surface area to volume of an object decreases sharply with increase in its size. The materials move across the cell rapidly because the cell has a larger surface area to volume ratio thus the rate of diffusion of materials is high.
Your image isn't clear so I couldn't see the proper option but lucky for you I have seen this question before so I will tell you the answer.
The answer is option D (facilitated diffusion).

Answer: Density Dependent Limitation
Explanation: Limitations to population growth are either density-dependent or density-independent. Density-dependent factors include disease, competition, and predation.
Answer;
Decreased birthrate
If immigration and emigration numbers remain equal , decreased birthrate could cause a slowed growth rate.
Explanation;
All populations change in size with time . Change in population is dependent of various factors, namely; birthrates, death rates, immigration and emigration.
Therefore; change in population size would be given by the difference of the sum of birth rates and immigration and the sum of death rates and emigration. That is; Change in Population Size = (Births + Immigration) - (Deaths + Emigration). A decreased birth rate with emigration and immigration remaining constant would cause a slowed growth rate.
