Vector $\overline{\mathrm{A}}$ has a magnitude of 3 units and vector $\overline{\mathrm{B}}$ has a magnitude of 4 units. If the magnitude of $\overline{\mathrm{A}}\times \overline{\mathrm{B}}$ is 6 units, then the angle between the two vectors is 

• A

  ${30}^0$

• B

  ${60}^0$

• C

  ${150}^0$

• D

  either ${30}^0$ or ${150}^0$
