Solution

(iii) C and D will produce a covalent bond.

The elements C and D belong to group 14 and group 17, respectively. We know that groups 14 and 17 consists of elements that are non-metallic in nature. When two non-metals combine, sharing of electrons takes place, which further results in the formation of a covalent bond.
