An air bubble of volume V₀ is released by a fish at a depth h in a lake. The bubble rises to the surface. Assume constant temperature and standard atmospheric pressure P above the lake. The volume of the bubble just before reaching the surface is    (d is the density of water).

• A

  ${\mathrm{V}}_0+\frac{\mathrm{hgd}}{\mathrm{P}}$

• B

  $\frac{{\mathrm{V}}_0(\mathrm{P}+\mathrm{hgd})}{\mathrm{P}}$

• C

  $\frac{{\mathrm{V}}_0}{\mathrm{P}}+\mathrm{hgd}$

• D

  $\left({\mathrm{V}}_0+{\mathrm{V}}_0\mathrm{dg}\right)$
