A monobasic acid (0.100 g) on complete combustion gave 0.252 g of $$\text{CO}_2$$ and 0.044 g of $$\text{H}_2\text{O}$$. For complete neutralization of 0.122 g of the acid, 10.0 mL of 0.1 M NaOH solution was required. Molecular formula of the acid is

A

$$\text{C}_7\text{H}_6\text{O}_2$$

B

$$\text{C}_6\text{H}_7\text{O}_2$$

C

$$\text{C}_7\text{H}_7\text{O}_2$$

D

$$\text{C}_6\text{H}_6\text{O}_2$$
