A cerebrum and cerebellum
B two lobes of cerebellum
C spinal cord with the brain
D two cerebral hemispheres

Verified Solution

Answer & Solution

Correct Answer

(D) two cerebral hemispheres

Step-by-step Solution

Detailed explanation

(D) two cerebral hemispheres,
Cerebrum forms the major part of the human brain. A deep cleft divides the cerebrum longitudinally into two halves, which are termed as the left and right cerebral hemispheres. The hemispheres are connected by a tract of nerve fibres called corpus callosum.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
