As we have learnt in

Cerebellum:

  • It is located behind the medulla oblongata and pons.
  • It consists of two lateral cerebellar hemispheres and central worm ­shaped part, the vermis.
  • The cerebellum has its grey matter on the outside, comprising three layers of cells and fibres. 
  • The grey matter of cerebellum exhibits tree-like structure called arbor vitae.
  • The middle layer contains character­istically large flask shaped Purkinje cells. 
  • The cerebellum also has Golgi cells, basket cells and granule cells.
  • It coordinates skeletal muscles to produce smooth, graceful motions.
  • The cerebellum controls rapid muscular activities, such as running, typing and even talking. 
  • All activities of the cerebellum are involuntary, but may involve learning in their early stages. 
  • Alcohol affects the cerebellum. Alcohol is a depressant, it inter­feres with the functions of the cerebellum.

Therefore, the grey matter of cerebellum exhibits tree-like structure called arbor vitae. Hence, the correct answer is option a.
