Match the following:
List-$I$ (Acid) List-$II$ ($K_a$ - Ionization Constant) $A$. $HCN$ $I$. $6.8 \times 10^{-4}$ $B$. $H_2C_2O_4$ $II$. $8.9 \times 10^{-8}$ $C$. $H_2S$ $III$. $4.9 \times 10^{-10}$ $D$. Niacin $IV$. $5.6 \times 10^{-2}$ $V$. $1.5 \times 10^{-5}$
The correct match is:
| List-$I$ (Acid) | List-$II$ ($K_a$ - Ionization Constant) |
| $A$. $HCN$ | $I$. $6.8 \times 10^{-4}$ |
| $B$. $H_2C_2O_4$ | $II$. $8.9 \times 10^{-8}$ |
