Solution

The correct option is C II and III
Graphite has delocalised electrons, just like metals. These electrons are free to move between the layers in graphite, so graphite can conduct electricity, while diamond and fullerene do have free electrons so they do not conduct electricity.

Hence, the correct answer is option (b).
