The correct Answer is:
To solve the question, we will evaluate each statement one by one and determine if they are true (T) or false (F). ### Step-by-step Solution: 1. **Statement i:** "Cerebellum forms the major part of human brain." - **Evaluation:** This statement is **False (F)**. The cerebrum, not the cerebellum, forms the major part of the human brain. The cerebrum is the largest part of the brain. - **Result:** F 2. **Statement ii:** "A deep cleft divided cerebrum transversely into two cerebral hemispheres." - **Evaluation:** This statement is also **False (F)**. The deep cleft that divides the cerebrum is called the longitudinal fissure, which divides it into two hemispheres longitudinally, not transversely. - **Result:** F 3. **Statement iii:** "The cerebral cortex is referred to as gray matter." - **Evaluation:** This statement is **True (T)**. The cerebral cortex is indeed referred to as gray matter due to its grayish appearance, which is primarily due to the presence of neuronal cell bodies. - **Result:** T 4. **Statement iv:** "Cerebral hemispheres are connected by tract of nerve fibre called corpus callosum." - **Evaluation:** This statement is **True (T)**. The corpus callosum is the bundle of nerve fibers that connects the left and right cerebral hemispheres, allowing communication between them. - **Result:** T ### Final Answer: - i. F - ii. F - iii. T - iv. T ### Summary: The correct answer is: - F, F, T, T
