An Electric Dipole of Moment Is Placed in a Uniform

An electric dipole of moment is placed in a uniform external electric field. The dipole moment vector is in the positive x direction. The external electric field vector is also in the positive x direction. When the dipole is aligned as shown, the net torque experienced by the dipole is

A) in the positive x direction.
B) in the positive y direction.
C) in the negative z direction.
D) zero.
E) described by none of these.
