The gauge pressure in the water at that point can be calculated using the formula:
P = ρgh
where P is the gauge pressure, ρ is the density of seawater, g is the acceleration due to gravity, and h is the depth of the water.

Substituting the given values, we get:
P = (1025 kg/m³) × 9.81 m/s² × 11,033 m
P = 1.11 × 10¹⁸ Pa

Therefore, the best choice is C, 1.11 × 10¹⁸ Pa.
