Answer:
If you are on a woodwind instrument:
The notes at the top represent one instrument's part and the notes at the bottom represent another one of the same instrument's part. if the two instruments play in unison, there should be a nice harmonic sound.
For example, if you had two trumpets playing this piece, one would play the higher octave and the other would play the lower octave.
If you are on a Piano:
You can play these notes at the same time.
Count carefully and look at the time signature, key signature, rests, and articulation!
Good luck!
I think A is the answer
