**Core Concept**
Hypoglycemia is a condition characterized by an abnormally low blood glucose concentration. It can be caused by factors that interfere with glucose production, increase glucose utilization, or cause excessive glucose loss.

**Why the Correct Answer is Right**
The correct answer is a medication that stimulates insulin release, thereby increasing glucose uptake by cells and lowering blood glucose levels. This medication acts by binding to pancreatic beta-cell receptors, stimulating the release of insulin, which in turn promotes glucose uptake by peripheral tissues.

**Why Each Wrong Option is Incorrect**
**Option A:** This medication is a sulfonylurea, which also stimulates insulin release, thereby causing hypoglycemia. It works by binding to ATP-sensitive potassium channels in pancreatic beta cells, closing the channels, and depolarizing the cells, leading to insulin release.

**Option B:** This medication is a biguanide, which increases insulin sensitivity and glucose uptake by peripheral tissues. It works by inhibiting mitochondrial glycerol-3-phosphate dehydrogenase, thereby reducing gluconeogenesis and increasing glucose uptake by peripheral tissues.

**Option C:** This medication is an alpha-glucosidase inhibitor, which delays carbohydrate absorption, thereby reducing postprandial glucose peaks. It works by inhibiting the enzyme alpha-glucosidase in the small intestine, which breaks down complex carbohydrates into simple sugars.

**Clinical Pearl / High-Yield Fact**
Medications that stimulate insulin release, such as sulfonylureas and meglitinides, can cause hypoglycemia as a side effect, especially when used in combination with other medications that increase insulin sensitivity or reduce glucose production.

**Correct Answer:** D
