Which among the following is vinylic halide?

Definition of Vinylic Halide: An organic compound where a halogen atom ($X$) is bonded directly to an sp$^2$ hybridized carbon that is part of a carbon–carbon double bond ($C=C$).

A) Haloalkane: The halogen is bonded to an sp$^3$ hybridized carbon, as in chloroethane ($CH_3CH_2Cl$), which does not satisfy the definition.

B) Haloalkene: Includes structures where the halogen is attached to a carbon in an alkene. Vinylic halides (e.g., chloroethene, $CH_2=CH-Cl$) are a subset, with the halogen on an sp$^2$ carbon of the double bond.

C) Haloalkyne: The halogen is bonded to an sp hybridized carbon in a triple bond, such as chloroethyne ($CH\equiv C-Cl$), not meeting the criteria.

D) Haloarene: The halogen is on an sp$^2$ carbon in an aromatic ring (e.g., chlorobenzene, $C_6H_5Cl$), but “vinylic” specifically denotes non-aromatic alkenes.

Thus, vinylic halides are a type of haloalkene, making B the correct classification.

Final answer: $\boxed{B}$
