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.

<span>Well the Dutch were the 1st country to recognize the colonies and being a major seafaring trader helped keep a starved and under supplied colonial army from late 1776 on,the French as a nation sold weapons and granted loans and towards the end landed an army used their fleet to run off the british and trapped Cornwallis at Yorktown,French citizens also volunteered to train the American army ,most notably LaFayette but there were many.Those are the only ones i know of but you have to understand that the world didn't exist as it did today their wasn't anything over here as far as nations that could assist and European nations were the only ones who could really be expected to have any interest so having French and Dutch assistance to of the biggest powers in Europe was really pretty good</span>
