Answer:
C. NH3
Explanation:
In case of ammonia molecule (NH3), there are 4 atoms of which N is the central atom and there are 3 hydrogen atoms.
If you could think of an axis of rotation that passes through the central Nitrogen atom and one of the hydrogen atoms, which also bisects the H-N-H angle, then you COULD have a C2 axis of symmetry. In order for this to be even possible, NH3 will have to be a triangular (trigonal planr) molecule with nitrogen at the center of the triangle, which would sort of look like a BF3 molecule.
