According to Pascal's law, pressure applied to a confined fluid is transmitted undiminished in all directions throughout the fluid. This means that when a change in pressure occurs at any point in the fluid, that change is felt equally at every other point within the fluid, regardless of the orientation. This fundamental principle explains why hydraulic systems, which are based on this law, can efficiently transfer force through liquids.

For example, in a hydraulic lift, applying a force at one point results in a proportional increase of force applied at another point within the system. This characteristic behavior differentiates Pascal’s law from concepts that would imply pressure is limited to a specific direction, such as only upward or downward, or suggest that it radiates outwards in a particular way rather than uniformly in all directions. The ability of pressure to be transmitted evenly through the fluid is why the correct answer is that it is transmitted in all directions.
