An air bubble of volume $V_0$ 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 touching the surface will be (density of water is $\rho$):

• A
  $V_0$
• B
  $V_0(\rho g h / P)$
• C
  $\frac{V_0}{1 + \frac{\rho g h}{P}}$
• D
  $V_0(1 + \frac{\rho g h}{P})$
