Generally we have to kinds of conductors
a) metallic conductors: which conduct electricity due to free movement of electrons
b) electrolytic conductors: which conduct electricity due to movement of ions.
HCN is an electrolyte and is non conducting in pure state as it has no free ions or electrons
When HCN is dissolved in water it dissociates as
These ions obtained due to dissociation of HCN makes it conducting in nature.
The delocalized cloud of π electrons in benzene is formed by the overlap of 6<u> p-orbitals</u>.
So, option B is correct one.
In the case of hydrocarbons, delocalisation occurs in benzene rings , where a hexagon of six carbon atoms has decalized electrons spread over the whole ring.
All of the carbon atoms in the benzene rings are orbitals around the ring produces a framework of six sigma bonds, while the unhybridized p-orbitals which are perpendicular to this plane over in side-to-side fashion to form three pi-bonds.
