Well, I'm not much of a physiologist, but, from a chemical point of view, nitric acid would be a too powerful oxidizing agent.

i assume HCl is the most logical option for stomach acid since the extracellular Cl- -concentration is very high: 108 mM.

Then using the H+/K+-ATPase H+ and Cl- combine to form HCl in the parietal cells. More about the physiology about gastric acid production can be found at the most loyal friend of every scientist: wikipedia.
