The predominant antibody of a typical primary immune response is IgM. Thus, option (b) is correct.
What is an antibody?
The protein the immune system of the body makes when it recognizes dangerous chemicals, known as antigens, is referred to as an antibody. These undesirable chemicals are removed from the human body by antibodies that bind to them.
The immune response is first challenged and for some non-peptide antigens, the term IgM is the predominant antibody. On successive interactions with the antigen, IgM may be the only isotype of antibody released.
As a result, the predominant antibody was the response of IgM.

Random neural firings. Tess tells myranda her dream is a result of brain activation during REM sleep.
Explanation:
This hypothesis is a neurobiological theory of dreams. The hypothesis was proposed by John Allan Hobson and Robert McCarley in 1977. The theory suggests that during sleep, the brain cerebral cortex's tries to make meaning of the neural activity happening in other parts of the brain when we sleep. Dreams are the result.
The cortex is what is responsible for the dream content. That is the person who who chased her, became a robot and how it later played laser tag with her.
