Explanation:
A is correct as Velocity includes the + and - signs, indicating the direction followed by the magnitude which is the speed.
B is Wrong. Velocity is <em>d</em><em>i</em><em>s</em><em>p</em><em>l</em><em>a</em><em>c</em><em>e</em><em>m</em><em>e</em><em>n</em><em>t</em><em> </em>divided by time.
