In a routine examination, some blood is taken and analyzed. The results show a high IgM titer for the mumps virus but a low IgG anti-mumps titer. This would indicate the person was recently infected with mumps.
This is the most common antibody. It is in the blood and other body fluids and protects against bacterial and viral infections. It may take time for IgG to form after infection or immunization. The presence of detectable IgG class antibodies indicates previous exposure to mumps virus through infection or immunization. Individuals who test positive are considered immune to the mumps virus. People with a history of mumps vaccination may not have detectable mumps IgM antibodies regardless of the timing of sample collection. IgG test results are usually positive and elevated at the initial blood draw.

Answer:
The answer is letter c, The structure of individual neurons.
Explanation:
Brain-imaging technique- <u><em>this comprises of different techniques for analyzing the brain's activities as well as structure, function and other problems.</em></u>
There are many brain-imaging techniques such as <u>Positron Emission Tomography or PET,</u> which traces the part of the brain that is activated during specific tasks as well as the localization of brain activity in response to a specific stimulus. These areas are seen with high radioactivity.
Patterns of blood flow in the brain can be detected by using <u>MRI (Magnetic Resonance Imaging) test.</u> There is an increase in blood flow to areas in the brain with high activity level.
With the explanation given, it shows that letter c is the only choice that the brain-imaging techniques cannot determine.
They help to prevent the disease from occurring. The immune system becomes familiar with the pathogen and learns how to fight it. Its the same process with vaccines
