D. Lipases

Answer 1

Hint: Cholesterol is abundantly found in the brain, nervous tissues, adrenal glands, and skin. Blood cholesterol has direct relations with the Heart. An increase in blood cholesterol levels may cause complications in normal heart conditions.

Complete answer:
Cholesterol in the blood is carried by a special transport protein called Lipoprotein. Cholesterol level in blood is regulated by many factors such as bad eating habits, lack of exercise, alcohol abuse, heredity, etc. Cholesterol is needed by the cells for growth but just in the right amount. High cholesterol levels can cause many problems including Heart attack. There are commercially available cholesterol-lowering agents for conditions like hypercholesterolemia such as Statin.
Statin: In patients who are at major risk of cardiovascular diseases, Doctors prescribe a class of drugs known as Statin. Statin is known to be helpful in the prevention of Cardiac diseases such a heart attack and heart stroke. They have been proved helpful in lowering the blood cholesterol level. Statin lowers the LDL which is known as bad cholesterol by reducing its production in the liver.

Therefore, the correct answer is (B) Statin.

Note:
There are two types of known cholesterol. LDL i.e. low-density lipoprotein and high-density lipoprotein or HDL. HDL falls under the good cholesterol category while LDL is bad cholesterol. LDL and HDL contribute to total cholesterol. LDL travels from the bloodstream to the cells and delivers the required cholesterol. Excess LDL gets collected at the arterial walls and forms a fatty deposit known as plaque. The deposition of plaque leads to the narrowing of the artery hence, it results in blood flow reduction which leads to many cardiac diseases.
