What would happen to a man whose pancreas has been surgically removed?

The pancreas is an important organ in the human body that produces insulin, a hormone that regulates the level of sugar in the blood. When the pancreas is surgically removed, the body loses its ability to produce insulin, and as a result, the level of sugar in the blood increases. This condition is called diabetes, which can lead to various complications if not managed properly. Therefore, option A is the correct answer. The other options are not related to the function of the pancreas, and thus, they are incorrect.
