A smooth inclined plane is inclined at an angle q with the horizontal. A body starts from rest and slides down the inclined surface. Then the time taken by it to reach the bottom is

• A

  $\sqrt{\left(\frac{2\mathrm{h}}{\mathrm{g}}\right)}$

• B

  $\sqrt{\left(\frac{2\mathrm{\theta }}{\mathrm{g}}\right)}$

• C

  $\frac{1}{\sin \mathrm{\theta }}\sqrt{\left(\frac{2\mathrm{h}}{\mathrm{g}}\right)}$

• D

  $\sin \mathrm{\theta }\{\sqrt{\left(2\mathrm{h}\right)}/\mathrm{g}\}$
