Answer
(c) Glucagon.
The islets of Langerhans contain two kinds of cell with OPPOSITE effects: ALPHA cells secrete GLUCAGON, which RAISES blood glucose by making the liver break glycogen down into glucose. BETA cells secrete INSULIN, which LOWERS blood glucose.
THE THREE SIMILAR WORDS must be kept apart, and the question offers all of them: GLUCOSE — the sugar itself GLYCOGEN — the stored form of glucose in the liver and muscles, a carbohydrate, not a hormone GLUCAGON — the HORMONE that releases glucose from glycogen Only glucagon is a hormone, so the other two can be eliminated on that ground alone.
An alphabetical aid: Alpha comes before Beta, and glucAgon before insulin — A with A.
