Weak dibasic acid H2CO3

B

Weak monobasic acid HO – CO2H

C

Weak diacid base CO(OH)2

D

Weak monoacid base HO – CO2H

Answer

Weak dibasic acid H2CO3

Explanation

Solution

CO2 (g) + H2O (l) $\longrightarrow$ H2CO3 (aq) ; H2CO3 $\rightleftharpoons$ H+(aq) + HCO3– (aq) ; HCO3– $\rightleftharpoons$ H+(aq) + CO32– (aq).
