Parents bring a toddler to the emergency department after she tripped and fell on the sidewalk. you note a submental laceration. as you evaluate this girl, you are most concerned about trauma to which other anatomic region?

I think the answer is Oral

Submental in the region of the mid part of the jaw. If there is laceration there, the toddler probably fall into the road by her chin. The nearest region of the chin would be oral or mouth. Otic is the ear and it is far from the chin so it is unlikely to be harmed. Orbital is the region of the eye, also far from the chin.
