• (ii), (iii) and (iv)

• (i), (ii) and (iv)

• (i), (iii) and (iv)

Answer 1

(i), (ii) and (iii)

Explanation:

The forebrain is the main thinking part of the brain and houses specialised centres for hearing, smell, memory, and sight. Involuntary actions like salivation, vomiting, and blood pressure are strictly controlled by the medulla in the hindbrain. Statement (iv) is incorrect because the cerebellum is actually the primary part of the brain that maintains body posture and balance.
