In a molecule of ammonia, pictured above, what can be said about the polarity and partial charges?

Choose one answer

Option A: A

Ammonia is a polar molecule, with a partial positive charge on the N atom and a partial negative charge on the H atoms.

Option B: B

Ammonia is non-polar, having no electronegative atoms and therefore no partial charges.

Option C: C

Ammonia is a polar molecule, with a partial negative charge on the N atom and a partial positive charge on the H atoms.

Option D: D

Ammonia is non-polar due to the geometry of the molecule.
