Assertion $(A)$ and the other is labeled as Reason $(R)$. Assertion $(A)$: $\mathrm{CH}_2=\mathrm{CH}-\mathrm{CH}_2-\mathrm{Cl}$ is an example of allyl halide
Reason$(R)$: Allyl halides are the compounds in which the halogen atom is attached to $\mathrm{sp}^2$ hybridised carbon atom.
In the light of the two above statements, choose the $most \ appropriate$ answer from the options given below:
| List I (Complex) | List $II$ (Type of isomerism) |
| $A$. $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5\left(\mathrm{NO}_2\right)\right] \mathrm{Cl}_2$ | $I$. Solvate isomerism |
| $B$. $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_5\left(\mathrm{SO}_4\right)\right] \mathrm{Br}$ | $II$. Linkage isomerism |
| $C$. $\left[\mathrm{Co}\left(\mathrm{NH}_3\right)_6\right]\left[\mathrm{Cr}(\mathrm{CN})_6\right]$ | $III$. Ionization isomerism |
| $D$. $\left[\mathrm{Co}\left(\mathrm{H}_2 \mathrm{O}\right)_6\right] \mathrm{Cl}_3$ | $IV$. Coordination isomerism |
