  • A

    $\left( {4 - \frac{1}{2}\sqrt 3 ,\,\,\frac{3}{2} - \sqrt 3 } \right)$

  • B

    $\left( {4 + \frac{1}{2}\sqrt 3 ,\,\,\frac{3}{2} + \sqrt 3 } \right)$

  • C

    $\left( {4 - \frac{1}{6}\sqrt 3 ,\,\,\frac{3}{2} - \frac{1}{3}\sqrt 3 } \right)$

  • D

    $\left( {4 + \frac{1}{6}\sqrt 3 ,\,\,\frac{3}{2} + \frac{1}{3}\sqrt 3 } \right)$
