Answer:
The most common elements, like carbon and nitrogen, are created in the cores of most stars, fused from lighter elements like hydrogen and helium. The heaviest elements, like iron, however, are only formed in the massive stars which end their lives in supernova explosions.
The mass of 
is 0.185 g.
To calculate the number of moles first calculate the molar mass of .
Molar mass of nitrogen and oxygen is 14 g/mol and 16 g/mol respectively
Thus, 
Now, number of moles can be calculated from mass and molar mass as follows:
Therefore, number of moles of 0.185 g is 0.0042 mol.
A proton is the same as an H+ ion, and Arrhenius acids are the ones that release H+ in solution, so the answer is A
