The ball first drops 8 meters to the surface. It then rebounds to a height of 4 meters. The ball then drops 4 meters to the surface and rebounds to a height of 2 meters. The ball then drops 2 meters to the surface and rebounds to a height of 1 meter. Finally, the ball drops 1 meter to the surface and does not rebound again. 
Therefore, the total distance the ball travels is 8 + 8 + 4 + 4 + 2 + 2 + 1 = 24. 
So, the best choice is B.
