Answer:
The correct answer is- a slow rise in the concentration of antibodies, followed by a rapid decline.
Explanation:
The first exposure of antibody in an organism generates the primary response. Initially, for some days after the exposure of antigen, there is no antibody detection in the blood and it is called the latent phase.
After the latent or lag phase, the antibodies start accumulating and reach to the peak between 7-10 days after exposure. So it takes a longer time to establish immunity in primary response.
After the immunity reaches the peak it declines rapidly that means higher immunity does not stay for a longer time. This phase is called the declining phase. Therefore, the correct answer is- a slow rise in the concentration of antibodies, followed by a rapid decline.

Morning jogs are one way to improve my activity level. One way to determine its effectiveness, is to pay attention to how long you can run at a time without needing to stop. Another way to improve physical activity, would be to spend an hour outside everyday. Whether it be to go on a walk, or play sports with friends. Being able to do this everyday would help my health very well!
You can write the rest about the details of what sports you would play, or where you would run to! You can also let me know where you would run and what sports and I can write the rest!!
