Air resistance (drag) acts opposite the projectile’s velocity, so it affects motion in both dimensions — horizontal and vertical. Drag reduces the speed (the magnitude of velocity) and thus:
- Reduces the horizontal component of velocity (decreasing range).
- Opposes downward motion too, reducing the downward speed/acceleration (so the fall is slower than in vacuum; a falling object can approach a terminal velocity).
If you must pick one of the offered choices, none are fully correct; the closest is “The air would affect the forward direction and would cause the speed of the object to decrease,” but note that air also reduces the vertical (downward) speed.
