When a small steel ball bearing falls through glycerine it quickly reaches a terminal velocity. This happens because the
- (A)viscous drag reduces to zero
- (B)upthrust on the ball bearing equals the viscous drag
- (C)weight of the ball bearing equals the upthrust acting on it
- (D)viscous drag increases as the velocity of the ball bearing increases
