Answer : The correct option is, electrons are not shared equally between atoms.

Explanation :

Polar covalent bond : It is a type of chemical bond in which a pair of electrons are not shared equally between the two atoms.

In polar covalent bond, the electrons are not shared equally because one atom spends more time with the electrons than the another atom. In this, one atom has more tendency to pull an electron than the other atom.

For example : $H_2O$ is an example of polar covalent bond. In water molecule, oxygen spends more time with the electron than the hydrogen and oxygen carries a partial negative charge.
