Solution
The correct option is C renin Secreted by the juxtaglomerular cells, renin (not to be confused with rennin, the digestive enzyme) is also known as angiotensinogenase. It is an enzyme and not a hormone. It helps to regulate the body's mean arterial pressure. It is secreted in response to a decrease in blood pressure. It causes a cascade of events ultimately leading to an increase in blood pressure.
