The correct Answer is:
To determine which statements about the brain are true, let's analyze each statement one by one: 1. **Statement (i): The main thinking part of the brain is the hindbrain.** - This statement is **false**. The main thinking part of the brain is the **cerebrum**, which is located in the **forebrain**. The hindbrain primarily controls basic life functions and coordination, not higher cognitive functions. 2. **Statement (ii): Centres of hearing, smell, memory, sight, etc., are located in the forebrain.** - This statement is **true**. The forebrain houses the **cerebrum**, which contains the centers responsible for hearing, smell, memory, and sight. Therefore, this statement accurately describes the location of these functions. 3. **Statement (iii): Involuntary actions like salivation, vomiting, blood pressure are controlled by the medulla in the hindbrain.** - This statement is **true**. The **medulla**, which is part of the hindbrain, regulates involuntary actions such as salivation, vomiting, and the control of blood pressure. Thus, this statement is correct. 4. **Statement (iv): Cerebellum does not control posture and balance of the body.** - This statement is **false**. The **cerebellum**, which is also part of the hindbrain, is crucial for maintaining posture and balance. Therefore, this statement is incorrect. **Conclusion:** - The true statements about the brain are: - Statement (ii): True - Statement (iii): True - The false statements are: - Statement (i): False - Statement (iv): False ### Summary of True Statements: - **True Statements:** (ii) and (iii) - **False Statements:** (i) and (iv)
