Answer:
A) polar
Explanation:
Polar molecules contains partial positive and partial negative charge as in all polar molecules two atoms have unequal sharing electron. Due to unequal sharing of electrons, one atom that attracts valence electrons strongly gains positive charge and other gain negative charge.
For example water, water is a polar molecule having partial negative and partial positive charge because the oxygen atom in water attracts electrons more strongly than the hydrogen atoms.
Hence, the correct answer is "A) polar".
