Solution

The correct option is C non-polar covalent bond
A purely covalent bond is formed when the electronegativity difference between two atoms is $0$ .

A non-polar covalent bond is formed when the electronegativity difference between two atoms is in the range $0.1$ to $0.8$ .

A polar covalent bond is formed when the electronegativity difference between two atoms is in the range $0.9$ to $1.8$ .

A $50$ % ionic and $50$ % covalent bond is formed when the electronegativity difference between two atoms is $1.9$ .

An ionic bond is formed when the electronegativity difference between two atoms is in the range $2$ to $3.2$ .

If the electro-negativities of two elements $A$ and $B$ are $2.1$ and $1.8$ respectively, then, the electronegativity difference is $0.3$ .

Hence, the type of bond formed between them is a covalent bond.

Hence, the correct option is $C$
