Stomach acid is known to have a very low pH, typically between 1.5 and 3.5, due to the presence of hydrochloric acid. This acidic environment is important for the digestion of food, particularly proteins. The other options listed - arterial blood, venous blood, and saliva - all have a pH level closer to neutral (around 7.4, 7.35, and 6.2-7.6, respectively).
