A
superior cerebellar peduncle
B
Middle cerebellar peduncle
C
Inferior cerebellar peduncle
D
None of the above
Explanation: 

Detailed explanation-1: -The connections between the cerebellum and other parts of the nervous system occur by way of three large pathways called cerebellar peduncles (Figures 19.1 to 19.3). The superior cerebellar peduncle (or brachium conjunctivum) is almost entirely an efferent pathway.

Detailed explanation-2: -The middle cerebellar peduncles contain afferent white matter projection fibers which originate in contralateral pontine nuclei. The corticopontocerebellar pathway is the predominant afferent fiber pathway that passes through the MCP.
