Solution
The correct option is C Medulla oblongata
The cerebrum and cerebellum are characterized by the location of the white matter beneath the grey matter. So, the grey matter forms the external layer. However, a reversal is seen in the brainstem region consisting of the pons and the medulla wherein, the white matter is external and the grey matter is internal. In some places, the white and grey matter are interwoven to form a reticulate structure. The white matter is the term used for the collection of the myelinated nerve fibres. The grey matter is used for the cell bodies and unmyelinated nerve fibres.Hence, the correct answer is 'Medulla oblongata'
