The structure that consists of a vermis and two lateral horns and is located in the posterior fossa is the?

Explanation:
The structure described is the cerebellum. Its hallmark layout includes a midline vermis that connects two lateral cerebellar hemispheres, all located in the posterior cranial fossa under the tentorium. The cerebrum consists of cerebral hemispheres and sits above the tentorium, not possessing a vermis. The pons and medulla oblongata are brainstem components in the posterior fossa but do not have a vermis or paired hemispheres. So the combination of a vermis plus two lateral hemispheres in the posterior fossa points to the cerebellum.
