| List $I$ Name of reaction | List $II$ Reagent used |
| $A$ Hell-Volhard-Zelinsky reaction | $I$ $NaOH + I _2$ |
| $B$ Iodoform reaction | $II$ (i) $CrO _2 Cl _2, CS _2$ (ii)$H _2 O$ |
| $C$ Etard reaction | $III$ (i) $Br _2 /$ red phosphorus (ii) $H _2 O$ |
| $D$ Gatterman-Koch reaction | $IV$ $CO , HCl$, anhyd.$AlCl_3$ |
Choose the correct answer from the options given below:
| Initial Conc. $(A)$ |
Initial Conc. $(B)$ |
Initial rate of |
| $0.1\,M$ | $0.1\,M$ | $1.2 \times 10^{-3}$ |
| $0.1\,M$ | $0.2\,M$ | $1.2 \times 10^{-3}$ |
| $0.2\,M$ | $0.1\,M$ | $2.4 \times 10^{-3}$ |
For the reaction the rate of formation of $C$ will be
