THE ANSWER IS A.

A tympanic membrane with distinctly impaired mobility has an adjusted likelihood ratio of 31. A tympanic membrane with slightly impaired mobility has an adjusted likelihood ratio of 4. A tympanic membrane with normal mobility is unlikely to be acute otitis media.

A distinctly red tympanic membrane (B) has an adjusted likelihood ratio of 8.4. A retracted tympanic membrane (C) has an adjusted likelihood ratio of 3.5. A ruptured tympanic membrane is nonspecific for acute otitis media. Another sign that suggests acute otitis media is a cloudy tympanic membrane with an adjusted likelihood ratio of 34.
