Correct Answer: Option A — Exponential growth
Conceptual Breakdown
The equation described represents Exponential Growth, often called geometric growth. Here is how it works in plain language:

The Process: This model assumes that a population has access to unlimited resources, such as food, water, and space. Because nothing is stopping the population from expanding, it grows faster and faster as the number of individuals increases.

The Result: This leads to a rapid "explosion" in numbers. When you look at this on a graph, it creates a J-shaped curve. The line starts relatively flat but eventually shoots almost straight up.

The Components: The rate of change in the population is determined by the "intrinsic rate of natural increase." This is essentially the birth rate minus the death rate. If the birth rate is higher than the death rate and resources are infinite, you get this specific type of growth.
