Inferior cerebellar peduncle
A
White matter of cerebellum
B
Ridges of the cerebellar cortex
C
Connect the cerebellum to the mid brain
D
Connect cerebellum to medulla oblongata
Explanation: 

Detailed explanation-1: -Each cerebellar inferior peduncle connects the spinal cord and medulla oblongata with the cerebellum, and comprises the juxtarestiform body and restiform body.

Detailed explanation-2: -Caudal cerebellar peduncle (restiform body) connects the cerebellum to the medulla oblongata. Afferent fibers: The caudal peduncle contains cerebellar afferent fibers from the lateral cuneate nucleus and dorsal spinocerebellar tract, from vestibular nuclei and nerve, and from the olivary nucleus (climbing fibers).

Detailed explanation-3: -The peduncles connect the cerebellum to the brainstem at the level of the medulla. The nuclei of several cranial nerves important to speech production can be found in the medulla, with their axons exiting the brain at this level.

Detailed explanation-4: -Cerebellar peduncles are the structure connecting the cerebellum to the brain stem and the cerebrum. There exist three cerebellar peduncles. The superior cerebellar peduncle (SCP) involves vestibular sense and proprioception connecting to the thalamocortical pathway.

Detailed explanation-5: -The middle cerebellar peduncle connects the pons to the cerebellum. It only contains fibres from the pons to the cerebellum. The fibers arise from the pontine nucleus, and travel to the opposite hemisphere of the cerebellar cortex.
