Choice A rationale:

Migraines and tension headaches are not mentioned as complications of otitis media in the text.

Otitis media primarily affects the middle ear and is associated with complications related to the ear and hearing.

Choice B rationale:

Chronic back pain and joint issues are unrelated to otitis media.

The complications of otitis media are primarily associated with the ear, hearing, and speech.

Choice C rationale:

Speech delay and hearing loss are mentioned as potential consequences of otitis media.

Otitis media can lead to hearing impairment, especially in children, which can subsequently cause speech delays.

This complication occurs due to the accumulation of fluid in the middle ear, which impairs the normal conduction of sound.

Choice D rationale:

Skin rashes and allergic reactions are not mentioned as consequences of otitis media.

Complications of otitis media primarily revolve around the auditory system and related functions.
