an acid with molecular formula `C_(7)H_(6)O_(3)` forms three types of sodium salt i.e., `C_(7)H_(5)O_(3)Na, C_(7)H_(4)O_(3)Na_(2)` and `C_(7)H_(3)O_(3)Na_(3)`. The basicity of the acid:

Options

A. one
B. Two
C. Three
D. Six

Explanation

To determine the basicity of the acid with the molecular formula \( C_7H_6O_3 \), we need to analyze the formation of its sodium salts and the number of ionizable hydrogen ions present in the acid.

### Step-by-Step Solution:

1. **Understanding Basicity**:
Basicity of an acid is defined as the number of ionizable (or replaceable) hydrogen ions (H⁺) in one molecule of the acid.

2. **Analyzing the Given Acid**:
