**Core Concept**
Acarbose is an anti-diabetic medication that belongs to the class of alpha-glucosidase inhibitors. It works by inhibiting the enzyme alpha-glucosidase, which breaks down carbohydrates into simple sugars, thereby slowing down carbohydrate absorption in the gastrointestinal tract.

**Why the Correct Answer is Right**
Acarbose specifically inhibits intestinal alpha-glucosidases, including sucrase-isomaltase, maltase-glucose 4-alpha-glucanotransferase, and glucoamylase, which are responsible for the breakdown of disaccharides and polysaccharides into monosaccharides. This action delays the absorption of glucose from the gut, leading to a decrease in postprandial blood glucose levels. Acarbose is particularly useful in managing type 2 diabetes, especially in patients with gastrointestinal symptoms.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because acarbose does indeed inhibit alpha-glucosidase enzymes, which is its primary mechanism of action.
**Option B:** This option is incorrect because acarbose does not stimulate insulin release; instead, it works by delaying carbohydrate absorption.
**Option C:** This option is incorrect because acarbose is not a sulfonylurea; it belongs to a different class of anti-diabetic medications.

**Clinical Pearl / High-Yield Fact**
Acarbose can cause gastrointestinal side effects such as flatulence, diarrhea, and abdominal discomfort due to the accumulation of undigested carbohydrates in the gut.

**Correct Answer: B. Acarbose does not stimulate insulin release.
