Coughing and sneezing are reflexes of the body
that prevent bacteria to further damage the organs inside the body. It helps in
keeping the airways clear and in healing. The two sources or passages of these
natural reflexes are the nose and the mouth.
<span>
Inside the nose, there are nasal hairs present to
filter the oxygen or air that we breathe in. These are called Cilia, these are
protective mechanisms of the body that trap dirt that cannot pass through the
respiratory system. Sneezing is a natural reflex that clears the nose passages
from obstructions that might affect the lungs. Coughing is also a natural
reflex that is generated by an irritation in the tonsils, this condition is
commonly viral. The tonsils are responsible for protecting the passage of dirty
air into the lungs.</span>

Answer:
The correct answer is option B. has a defective allele and normal phenotype.
Explanation:
Genetic carrier or the hereditary carrier is an organism or a person that has a recessive allele for a particular trait or character (generally mutation) but does not exhibit the trait or any character related to the trait.
The carriers are normal in the sex-linked characters in comparison to the autosomal traits. Females are generally the carrier for sex-linked characters and carry the allele to the next generation.
Thus, the correct answer is option B. has a defective allele and normal.
