Hint: pH is a determining factor of acidity and basicity of any species. The pH range lies between $7$ to $14$. The species which is strongly acidic has pH less than seven and the species which is basic has a pH of greater than seven.
Complete Step by Step Solution:
pH of any species gives us an idea about the acidity and basicity of that species. The pH range lies from $7$ to $14$. Any species that have pH less than seven are acidic and acidity increases as the pH value of the species decreases from seven. Again any species that have pH greater than seven are basic and basicity increases as the pH value of the species increases from seven.
Stomach is an important part of our body. It helps to digest food we consume everyday.
Our stomach contains hydrochloric acid. Hydrochloric acid is a strong acid. Hydrochloric acid has a pH of $2.0$. Thus our stomach has a pH of $2.0$ as it is strongly acidic.
Thus the correct option is $B$.
Note: Stomach digests the food we consumed daily. Stomach contains hydrochloric acid which helps to digest the food. Thus the pH of our stomach depends on the pH value of hydrochloric acid. As hydrochloric acid is a strong acid and has a pH of $2.0$ so, the pH of the stomach is also $2.0$.
