The correct answer is option 1 - High Density Lipoprotein (HDL). HDL is commonly referred to as "good cholesterol" because it helps to remove excess cholesterol from the blood vessels and carries it back to the liver for processing. This process reduces the risk of plaque buildup in the arteries and lowers the risk of cardiovascular diseases and hypertension.

Option 2 - Low Density Lipoprotein (LDL) is often referred to as "bad cholesterol" because it can contribute to the buildup of plaque in the arteries, increasing the risk of cardiovascular diseases and hypertension.

Option 3 - Triglyceride is a type of fat found in the blood. High levels of triglycerides can be a risk factor for cardiovascular diseases and hypertension, but it is not specifically considered "good cholesterol" like HDL.

Option 4 - Fatty acids are the building blocks of fats. While some fatty acids, such as omega-3 fatty acids, have been associated with cardiovascular health benefits, they are not considered "good cholesterol" like HDL.

Therefore, the correct answer is option 1 - High Density Lipoprotein (HDL).
