Answer:
C. The atoms share electrons, but the electrons spend more time around that area of the molecule.
Step-by-step explanation:
In a polar covalent bond between two non-metals electrons are shared. The two non-metals in the covalent bond have a difference in electronegativity. The atom with higher electronegativity attracts the shared pair of electrons more towards itself thus gaining a partial negative charge, and the other atom in the bond gains a partial positive charge.
