Allotropes of Carbon

The INCORRECT statement regarding the structure of ${\mathrm{C}}_{60}$ is :

The number of pentagons in ${\mathrm{C}}_{60}$ and trigons (triangles) in white phosphorus, are;

${\mathrm{C}}_{60},$ an allotrope of carbon contains

The $\mathrm{C}-\mathrm{C}$ bond length is maximum in:

Assertion: Among the carbon allotropes, diamond is an insulator, whereas, graphite is a good conductor of electricity.

Reason: Hybridization of carbon in diamond and graphite are $\mathrm{s}{\mathrm{p}}^3$ and $\mathrm{s}{\mathrm{p}}^2$ respectively.
