Explanation:

Let's explore the options:

- Pascal's Law: This states that pressure applied at any point to a confined fluid is transmitted undiminished throughout the fluid. Hydraulic presses work on this principle.

- Bernoulli's Principle: It explains how an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy. It doesn’t relate to hydraulic presses.

- Archimedes' Principle: This principle is about buoyancy and states that any body completely or partially submerged in a fluid is acted upon by an upward force equal to the weight of the fluid displaced by the body.

- Boyle’s Law: It describes the inversely proportional relationship between the pressure and volume of a gas at constant temperature.
