NEET 2023, Chemistry Q30: Properties of Alkyl Halides (Halo Alkanes) & Aryl Halides (Halo Arenes)

The halogen X is attached to an $s{p}^3$ carbon that is itself attached to a C=C double bond — that is the defining geometry of an allylic halide.

Aryl: halogen on the aromatic ring; vinylic: halogen on the C=C carbon itself; benzylic: halogen on the carbon directly attached to the ring.
