Which among the following is an allylic halide?

Column-$(I)$ contains the formula of an alkyl halide and Column-$(II)$ contains its type. Match Column-$(I)$ with Column-$(II)$.

Column-$(I)$	Column-$(II)$
$(A)$ $CH_3CH_2X$	$(1)$ $4^{\circ}$ halide
$(B)$ $R'CH_2X$	$(2)$ $3^{\circ}$ halide
$(C)$ $R'R''CHX$	$(3)$ $2^{\circ}$ halide
$(D)$ $R'R''CR'''X$	$(4)$ $1^{\circ}$ halide

Given below are two statements,one is labeled as Assertion $(A)$ and the other is labeled as Reason $(R)$.
Assertion $(A)$: $CH_2=CH-CH_2-Cl$ is an example of an allyl halide.
Reason $(R)$: Allyl halides are the compounds in which the halogen atom is attached to an $sp^3$ hybridized carbon atom,which is adjacent to a carbon-carbon double bond.
In the light of the two above statements,choose the most appropriate answer from the options given below:
