Correct answer: D (i)-R, (ii)-Q, (iii)-P, (iv)-S, (v)-T

This question requires matching different brain parts with their specific characteristics, locations, or functions as described in the NCERT text. (i) Cerebrum: Forms the major part of the human brain, longitudinally divided into two cerebral hemispheres. So, (i) matches (R). (ii) Thalamus: It is a major coordinating centre for sensory and motor signaling. So, (ii) matches (Q). (iii) Hypothalamus: It contains a number of centres which control body temperature, urge for eating and drinking. So, (iii) matches (P). (iv) Midbrain: It is located between the thalamus/hypothalamus of the forebrain and pons of the hindbrain. Its dorsal portion consists of corpora quadrigemina. So, (iv) matches (S). (v) Medulla oblongata: It contains centres which control respiration, cardiovascular reflexes and gastric secretions. So, (v) matches (T). Based on these matches, the correct option is D
