Incorrect Statements Regarding Allotropes of Carbon:

Diamond is ionic but graphite is covalent:
- This statement is incorrect because both diamond and graphite are composed of carbon atoms bonded together through covalent bonds. There are no ionic bonds present in either allotrope.

Diamond has a layered structure while graphite has a network structure:
- This statement is incorrect as diamond has a three-dimensional network structure where each carbon atom is bonded to four other carbon atoms in a tetrahedral arrangement. On the other hand, graphite has a layered structure where carbon atoms are arranged in hexagonal rings that are stacked on top of each other.

Therefore, the correct answer is option 'D' as statements II and IV are incorrect.
