{'acids': [1, 0, 0, 4], 'nitric acid': [0, 0, 0, 2], 'formic acid': [0, 1, 0, 0], 'hydrochloric acid': [1, 0, 3, 0], 'sulphuric acid': [1, 1, 0, 1], 'human stomach': [0, 0, 0, 1]}

The correct answer to the question, "Which one of the following acids is produced in the human stomach?" is option 4, Hydrochloric acid.

Let`s explain why other options are not correct:

Option 1 is Formic acid. This acid is not produced in the human body naturally. It is generally found in ants and stinging nettles.

Option 2 suggests Sulphuric acid. It is a very strong acid used in labs and industries, and it`s not produced in our body.

Option 3 is Nitric acid, which is also a strong acid and not produced in the human body. It`s used in fertilizers, explosives, etc.

Finally, option 4 is Hydrochloric acid, which is the correct answer. The stomach linings of humans produce gastric acid composed of hydrochloric acid (HCl), potassium chloride (KCl), and sodium chloride (NaCl). This acid aids in the process of digestion.

So, the correct answer is Hydrochloric acid.
