Answer:
C.) Selective pressure
Explanation:
Selective pressure is a natural process that occurs in nature in which certain phenotypes are favored in certain environments. When we say these phenotypes are favored, this means individuals with these phenotypes have a better chance at survival and reproduction in particular environments. Certain phenotypes may be beneficial in some environments but harmful in others.
Based on the CDC guidelines a person with a CD4+ cell count between 200-400 is regarded as being in <u>the second stage</u> of the HIV infection.
Acquired Immunodeficiency Syndrome
Acquired immunodeficiency syndrome (AIDS) is a condition caused by HIV (human immunodeficiency virus). AIDS is a chronic disorder and can become life-threatening for the infected person. The HIV viruses reproduce inside the host and while doing so they destroy the CD4+ immune cells which reduce the person's ability to fight against other diseases.
CD4+ cell count and AIDS
According to the CDC (U.S. Centers for Disease Control and Prevention), HIV infection is categorized into different stages based on the number of CD4+ cells.
- Stage 1: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
- Stage 2: - CD4+ cell count is more than 500 per microlitre. There are no symptoms or AIDS-related conditions.
- Stage 3: - The CD4+ cell count falls below 200 and AIDS-related symptoms and conditions are present.

<h3>What is Competition in the population?</h3>
Competition in population may be defined as the existence of two or more same or different species that are actively fighting over the same resources and factors that they disseminate.
Competition and predation are the two types of species interaction through which the population of species either increases or decreases.
According to the given chart, it is noticeable that the population drop in predator cheetah and lion populations because of the reduction in zebra lowering population but the in cheetah population is additionally than that of the lion.
Therefore, the correct option for this question is A.
