Correct Answer: Option C

Explanation

In 1902, the British physiologist Ernest Henry Starling and his student William Bayliss discovered hormones. They found that a substance secreted by the cells of the duodenum (the first part of the small intestine) could stimulate the pancreas to produce digestive enzymes. They called this substance "secretin" and realized that it was a hormone, a chemical messenger that travels through the bloodstream to act on target cells in other parts of the body. This discovery paved the way for the study of endocrinology, the branch of biology that deals with hormones and the endocrine system.
