Basicity of boric acid, H3BO3 is A. 2 B. 3 C. 4 D. 5

The correct answer is $\boxed{\text{A}}$. Boric acid, $H_3BO_3$, is a weak monobasic acid. This means that it can only donate one proton, or hydrogen ion, in a chemical reaction. The following equation shows the reaction of boric acid with water:

$$H_3BO_3 + H_2O \rightleftharpoons H_3O^+ + H_2BO_3^-$$

In this reaction, one
