Answer 1

The correct statement that best explains the difference between polar and nonpolar covalent bonds is:

Polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally.

This is because in polar covalent bonds, one atom has a higher electronegativity than the other, resulting in an unequal sharing of electrons, while in nonpolar covalent bonds, the atoms involved have similar electronegativities and share electrons more equally.
