• C. Assertion is correct but reason is incorrect.
• D. Both assertion and reason are incorrect

Answer 1

The correct option is A Both assertion and reason are correct and reason is the correct explanation for assertion.

• Hepatectomy involves removing of the liver, which is like the metabolism factory of our body.
• In glucose metabolism liver helps via saving excess glucose via glycogenesis and acting like a buffer and providing glucose via gluconeogenesis when low.
• The pancreas secretes the hormone insulin which helps the body tissues to use glucose, insulin acts as the gateway to use glucose.
• But when the liver is removed, that means u can't store extra glucose and it will remain in the blood and when glucose is required or low in blood, it won't be available for use when you want as the storage is absent. Hence, Blood sugar levels fall rapidly after hepatectomy as the glycogen of the liver is the principal source of blood sugar.

So, the correct answer is 'Both assertion and reason are correct and the reason is the correct explanation for assertion'.
