Option C

Explanation:

Insulin and glucagon helps in the regulation of the blood sugar level. The level of the sugar in the blood has to be maintained. This level is maintained by the help of the hormones insulin and glucagon.

The role of insulin is to lower down the level of sugar in the blood. The carbohydrate is converted into glucose. This triggers the hormone insulin to be released so that the excess of the glucose gets stored in the muscle and liver cells.

After, 4 to 5 hours of eating when the level of glucose in the bloodstream decreased then the hormone glucagon is released from the pancreas which breaks down the glucose stored in the muscle and liver cells.

This is how the level of sugar in the blood is maintained.
