Show answer and explanation

Correct answer: (C) P-ii, Q-iv, R-i, S-iii

Explanation

White matter is made of the fibre tracts under the cortex (ii). Spikes are the electrical impulses of neurons (iv). Gray matter is the folded sheet of neuron cell bodies on each hemisphere (i). A fissure is a groove in the cortex (iii). So P-ii, Q-iv, R-i, S-iii.
