You forgot one...and that happens to be the answer---> Accuracy
Answer:
D i think. Not sure.
Explanation:
I mean i just did it myself, and i dont really do chemistry, but I would say D sorrry if i made you get it wrong!!
I would say Na. Oxygen has 2 valence electrons and when reacting with other molecules, the ones with the fullest or emptiest shells will react the least. Both H2 and Na are in the Alkali Metals in the first row, but since H2 has 2 molecules, it would use more oxygen than Ana
