The electric dipole will try to orient in a direction opposite to the external electric field.

(C) The third statement is incorrect. An electric dipole in an external electric field experiences a torque that tends to align the dipole moment $p$ in the direction of the external electric field $E$. This alignment corresponds to the state of minimum potential energy $(U = -p \cdot E)$ and maximum stability. Therefore, the dipole does not orient itself in the opposite direction.
