Match different cells of Islets of Langerhans in Column-I with their role in Column-II. Select the correct answer from the options given below.

	Column I		Column II
A.	Alpha cells	I.	Stimulates muscles for glycogenesis.
B.	Beta cells	II.	Decreases gastric secretions and absorption in digestive tract.
C.	Delta cells	III.	Inhibits the release of pancreatic juice.
D.	F cells	IV.	Stimulates liver for glucogenolysis.

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.
