The only quantity that stays unchanged (no acceleration in that direction) is the horizontal component of the velocity. In symbols:- If the launch speed is $u$ at an angle $\theta$ above horizontal,$v_x=u \cos \theta$and since there's no horizontal acceleration, $v_x$ remains the same at all times and positions.So the correct choice is:Option B: Horizontal component of velocity.
