Answer: B

Step-by-step solution

The compound shown is $\ce{CH2=CH-CH2-Cl}$ . The halogen $\ce{Cl}$ is attached to the $\ce{CH2}$ group, which is the carbon adjacent to the $\ce{C=C}$ double bond. This $\ce{sp^3}$ carbon next to the double bond is called the allylic carbon. Hence, the compound is an allylic halide. Therefore, the correct answer is B.
