A) the value of the torque divided by the value of the angular acceleration at a certain instant.
B) the value of the torque multiplied by the value of the angular acceleration at a certain instant.
C) the area bounded by the curve and the torque axis.
D) the area bounded by the curve and the angular acceleration axis.
E) the slope of the curve.
