• A. Widening arteries by thinning their walls
• B. Narrowing veins by carbohydrate deposition
• C. Narrowing arteries by fat deposition
• D. Narrowing arteries by carbohydrate deposition

Answer 1

The correct option is C Narrowing arteries by fat deposition

• Cholesterol and other fats travel in the bloodstream in the form of lipoproteins.
  
• Saturated fats in the diet raise the level of LDL (low-density lipoprotein) cholesterol in the blood.
• This LDL cholesterol is called bad cholesterol.
• It forms a plaque-like substance on the walls of arteries which causes the narrowing of arteries.
• Thus, it blocks the natural flow of blood and causes a severe risk for heart attack and stroke. So, the correct answer is 'Narrowing arteries by fat deposition'.
