The right answer is C. I think, a. and d. are obviously not serious. B is not true, because Ag and Au are in the same group in the periodic table and therefore have the same number of electrons in the last level. So, they form ions with the same charge. C is true beacause Ag and Au have different numbers in the periodic table and different amount of protons and neutrons in their nucleuses.
The correct answer is choice B, Tt. I hope this helps.

Explanation:
Animal fats and hydrogenated vegetable margarine contain saturated triglycerides. Saturated triglycerides are those that are made of saturated fatty acids. These saturated fatty acids are capable of forming atheroma (/plaques) along arterial walls, causing atherosclerosis or arteriosclerosis. These could both result in coronary thrombosis (blocking of a coronary artery by a clot of blood), and hence a myocardial infarction (heart attack).
