 As we learned

 

Graphite -

C atom is sp2 hybridised and thermodynamically more stable than diamond at ordinary temperature 

- wherein

High electrical conductivity is due to presence of delocalised \pi - electron cloud.

 

 

Diamond -

C atom is sp3 hybridised and has three dimensional network structure

- wherein

It is bad conductor due to absence of valence electron 

 

 Graphite
Sp^{2} hybridization 

%p = \frac{2}{3}\times 100

=  67%

Diamond 

Sp^{3} hybridisation 
% p = \frac{3}{4}\times 100

= 75 %


Option 1)

33 and 25

Option 2)

33 and 75

Option 3)

50 and 75

Option 4)

67 and 75
