Solution
The correct option is A
all the four valence electrons are bonded to carbon atoms by covalent bonds
Explanation:
Covalent bond: A covalent bond is formed by the equal sharing of electrons from both the participating atoms. The pair of electrons participating in this type of bonding is called shared pair or bonding pair.
In diamond, each carbon atom is sp3 hybridized and each carbon atom in the diamond crystal is linked to four other carbon atoms by strong covalent bonds.
The four surrounding atoms are at four vertices of a regular tetrahedron. This rigid structure of diamond makes it a very hard substance.
