Otitis media is generally caused by dysfunction of the Eustachian tube, which can be due to Pharyngitis.
Explanation:
The otitis media is an infection or inflammation of the middle ear and is mostly caused by the inflammation of the mucous membranes in the nasopharynx leading to dysfunction of the Eustachian tube. This can be caused due to a upper respiratory tract viral infection or streptococcal pharyngitis (strep throat) or due to some allergy.
Pharyngitis or sore throat is a type of inflammation caused by upper respiratory tract viral infection.

Answer: d. Confounding
Explanation:
In the context of a scientific study such as this one, a confounding factor is one that has influence on both the exposure and event variable(s), which may lead to over- or underestimation of the direct relationship between them (if any).
For instance: In this example, researchers may have had reason to believe that male gender is associated with both higher risk of obesity (the exposure variable) and adult-onset asthma (the event variable). If gender is not taken into account, one may claim that the finding of an association between obesity and asthma is simply an artifact due to the high proportion of male patients (likely to present with both). <em>Controlling</em> for that variable (such as by matching, as in this example) allows researchers to test for this hypothesis.
