Solution

The correct option is C II and III
Forebrain contains centres for visual, auditory, tactile, olfactory, and temperature reception. It is also involved in the intelligence, memories, perception, and voluntary movements of a person. Similarly, all involuntary actions are majorly regulated by the medulla portion of the brain.
