Low blood glucose levels

High blood calcium levels

Increased blood pressure

Elevated insulin levels

Verified step by step guidance

Step 1: Begin by understanding the role of glucagon in the body. Glucagon is a hormone produced by the alpha cells of the pancreas, and its primary function is to increase blood glucose levels by stimulating glycogen breakdown in the liver.

Step 2: Identify the primary stimulus for glucagon release. Glucagon is released in response to low blood glucose levels, which signals the body to restore glucose homeostasis.

Step 3: Evaluate the options provided in the question. Low blood glucose levels directly trigger glucagon release, while the other options (high blood calcium levels, increased blood pressure, and elevated insulin levels) are not directly related to glucagon secretion.

Step 4: Recall the physiological feedback mechanism. When blood glucose levels drop, the pancreas detects this change and releases glucagon to counteract hypoglycemia by increasing glucose availability.

Step 5: Conclude that the correct answer is 'Low blood glucose levels,' as it aligns with the primary function and stimulus of glucagon secretion.
