The correct answer is option 3 - HDL.

This is because HDL, also known as high-density lipoprotein, is often referred to as "good cholesterol". HDL helps to remove excess cholesterol from the bloodstream and transport it to the liver, where it can be broken down and eliminated from the body. Higher levels of HDL have been associated with a lower risk of developing heart disease.

On the other hand, options 1 and 2 - VLDL and LDL, are often considered "bad cholesterol" because they can contribute to the buildup of plaque in the arteries, leading to increased risk of heart disease. Option 4 - triglycerides, while not considered cholesterol, are a type of fat in the blood that can also contribute to heart disease when levels are too high.

Therefore, HDL is generally considered the best cholesterol to have in the body.
