This process is referred to as Ammonification, I believe, basically this allows Nitrogen to be in the appropriate form for plants to absorb it.
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 answer for this is carbohydrates.
