i. Forebraina. for vital activities like respiration, circulation, digestion
ii. Midbrainb. for integrating the activities of nervous system
iii. Hindbrainc. for visual and auditory reflex

Choose the most appropriate option from below :

  • A.i-b, ii-c, iii-a
  • B.i-c, ii-b, iii-a
  • C.i-c, ii-a, iii-b
  • D.i-a, ii-c, iii-b

Answer: A

The correct matching is i-b, ii-c, iii-a.

The forebrain, with the cerebrum and thalamus, integrates the activities of the nervous system and is the seat of thinking, memory and voluntary action (b). The midbrain contains the centres for visual and auditory reflexes, such as turning the head towards a sudden sound or light (c). The hindbrain, through the medulla, controls vital activities such as breathing, circulation and digestive reflexes (a).

Every other option gives the vital centres to the forebrain or midbrain.
