Which of the following are correct expression for torque acting on a body?
A. $\vec \tau = \vec r \times \vec L$
B. $\vec \tau = \frac{d}{{dt}}(\vec r \times \vec p)$
C. $\vec \tau = \vec r \times \frac{{d\vec p}}{{dt}}$
D. $\vec \tau = I\vec \alpha $
E. $\vec \tau = \vec r \times \vec F$
($\vec r = $ position vector; $\vec p = $ linear momentum; $\vec L = $ angular momentum; $\vec \alpha = $ angular acceleration; $I = $ moment of inertia; $\vec F = $ force; $t = $ time)
