Hint: Covalent bond is formed between two atoms. This is a strong bond formed by sharing electrons between the atoms. This bond depends on various factors like electronegativity difference, size of the atoms etc.
Complete step by step solution:The covalent character of a covalent bond depends on various factors like size of the cations and anions, electronegativity difference of the atoms. The covalent character of a bond depends on the electronegativity difference of the atoms forming the bond. As the electronegativity difference of a bond decreases its covalent character increases.
Let us take an example of two covalent bonds. One is between carbon and sulfur atom and another one is between carbon and oxygen atom.
From the Pauling electronegativity scale we can get the values of electronegativity of the carbon atom as $2.5$ and the oxygen atom as $3.5$ . Thus the electronegativity difference for the carbon oxygen covalent bond is $3.5-2.5=1$ . Thus it is a weak covalent bond.
From the Pauling electronegativity scale we can get the values of electronegativity of the carbon atom as $2.5$ and the sulfur atom as $2.5$ . Thus the electronegativity difference for the carbon sulfur covalent bond is $2.5-2.5=0$ . Since the electronegativity difference between carbon and sulfur is zero. Thus the carbon sulfur bond is a strong covalent bond.
Thus the correct option is A.
Note: Covalent bond does not depend on charge of the atoms. The atoms which exist as ions like the metal atoms do not participate in the formation of covalent bonds.
