The appropriate answer is b. Pressure increases with depth because it must support the fluid weight above it. Pressure is defined as force per unit area. This means the deeper the water the greater the pressure at the floor if the ocean.

Scientists studying the deepest sections of the ocean must have specialized equipment to survive the crushing depths. Animals who dive to extreme depths like whales must have specialized adaptations to do this.
