A container shown in figure contains a liquid to a depth H, and of density $\mathrm{\rho }$. The gauge pressure at point P is:

• A

  $\frac{\mathrm{\rho gH}}{2+{\mathrm{P}}_0}$

• B

  $\frac{\mathrm{\rho gH}}{2}$

• C

  $\frac{\mathrm{\rho gH}}{2\mathrm{cos\theta }}$

• D

  $\frac{\mathrm{\rho gH} \mathrm{cos\theta }}{2}$
