In a compartment that has been completely flooded, the greatest pressure will be exerted __________.

Correct Answer: Option D — along the bottom of any bulkhead

Hydrostatic pressure in a flooded compartment increases linearly with depth, defined by the formula P = ρgh. Consequently, the pressure is greatest at the lowest point of the compartment. Therefore, the bottom of any bulkhead experiences the maximum force, requiring robust structural integrity to prevent catastrophic failure.
