(C) The stability of a carbocation depends on its ability to achieve a planar $sp^2$ hybridized geometry at the positively charged carbon atom.$A$. Triphenylmethyl carbocation is highly stable due to resonance.$B$. Cyclohex$-1-$en$-1-$yl cation is a vinyl cation,which is less stable but can exist.$C$. Bicyclo[$2.2$.$1$]heptan$-1-$yl cation (a bridgehead carbocation) is extremely unstable because the rigid bicyclic structure prevents the positively charged carbon from achieving the required planar $sp^2$ geometry (Bredt's rule).$D$. Vinyl cation $(CH_2 = \mathop C\limits^ + H)$ is also less stable but more feasible than a bridgehead carbocation in a small bicyclic system.Therefore,the bridgehead carbocation is the least likely to form.
