Since the bullet is fired horizontally, there is no initial vertical velocity. Therefore, the only motion is in the horizontal direction. In one second, the bullet will travel a distance equal to the product of its velocity and the time traveled. Therefore, the distance downrange is:
distance = velocity x time = 100 m/s x 1 s = 100 m
Therefore, the answer is C, 100 m.
