Answer:
1-) Patent ductus arteriosus: this duct normally must be closed two days after the baby is born, but if not, it will carry oxygenated blood to the pulmonary artery producing a mixture with oxygen-poor blood and producing a cardiac overload due to the large amount of blood that would reach the right heart.
2-) Transposition of the great vessels: In this defect, the oxygenated blood is collected throughout the body and taken directly to the right heart which returns to the poorly connected aorta (right ventricle) back to the body without oxygenation; on the other hand, the oxygenated blood returns to the left heart, then goes to the pulmonary artery (connected to the left ventricle) and back to the lungs.
3-) Tetralogy of fallot: It is a congenital anomaly that can present different defects at the level of the heart, such as:
- intraventricular communication, in which blood would go from the left heart to the right heart.
- Pulmonary obstruction, there is obstruction of the blood outlet by plugging the duct, which causes a decrease in blood flow to the body.
- Dextraposition of the aorta: The aorta is more deviated to the right and in union with the intraventricular (IVC) communication. Increased amount of bleeding to the pulmonary artery. Bad oxygenation of the blood due to the mixture thereof.

Dietary supplements may also help athletes who are gaining weight or who need to address known nutritional deficiencies.
Some of the most studied include protein creatine caffeine bicarbonate and beta-alanine. No supplements are required. Instead, whole foods and a balanced nutrition plan provide the right amount of key nutrients needed to be a healthy athlete and perform at peak performance can.
These extra ingredients may seem like a good idea, but the more ingredients the higher the chance of unwanted side effects. Start with only the vitamins or minerals you want to take. Don't buy more than you need. Too much vitamin A can cause headaches and liver damage, reduce bone strength and cause birth defects. Excess iron can cause nausea and vomiting and damage the liver and other organs.

Answer:
(B). inhibiting HMG-CoA reductase.
Explanation:
Lovastatin is a drug, which is used to reduce risk for cardiovascular diseases and to reduce level of cholesterol in blood.
It works by inhibiting HMG-CoA reductase (3-hydroxy-3-methylglutaryl-coenzyme A reductase) enzyme, required for the formation of mevalonate from HMG-CoA.
Mevalonate is building block for the biosynthesis of cholesterol. Hence, lovastatin inhibits cholesterol production by inhibiting synthesis of mevalonate.
Thus, the correct answer is option (B).
