Answer:
A. When moving inwards towards the ball, step your right foot forward positioning your right leg under the table.
B. So starting from the ready position, to move from the backhand to the forehand (for a right hander), you move your left foot first, then your right foot, then your left foot again and then your right.
C. As the name suggests, your legs cross over each other for you to reach and catch the oncoming ball at a faster pace.
