A diver becomes trapped while exploring a cave in the ocean. Inside the cave an air pocket formed, as shown in the figure, where the diver took shelter. During the rescue, to prevent damage to his body, it was necessary for the diver to undergo a decompression process before returning to the surface so that his body would be under atmospheric pressure again. The graph shows the relationship between the recommended decompression times for individuals in this situation and the pressure variation. Consider that the acceleration due to gravity is equal to $10\mathrm{~m~s^{-2}}$ and that the density of water is $\rho = 1000\mathrm{~kg~m^{-3}}$. In minutes, what is the decompression time to which the diver should be subjected? (A) 100 (B) 80 (C) 60 (D) 40 (E) 20
