Solution

The correct option is D The Assertion is incorrect but the Reason is incorrect
Vinylic halides are unreactive towards nucleophilic substitution reaction. In practice, halogen atoms of vinyl halides are found to be inert.
The vinyl halide is the resonance hybrid of the following two structures.
$C H_{2} = C H - X ⟷^{-} C H_{2} - C H = X^{+}$
Due to this, $C - X$ bond acquires partial double bond character. The halogen atom is more firmly attached to $C$ and cannot be easily replaced.
Reactivity is due to the polarity of the carbon-halogen bond.
More polar is the $C - X$ bond, more reactive is the halide and vice versa.
Hence, Assertion is incorrect but the Reason is correct.
