Explanation:
Pascal's law states that when there is an increase in pressure at any point in a confined fluid, there is an equal increase in pressure throughout the container. This law is applicable in various practical applications, such as:

1. Brahma Press:
- Brahma Press is a hydraulic press that utilizes Pascal's law to exert a large force with the application of a small force.
- It consists of two connected cylinders, one with a larger cross-sectional area and the other with a smaller cross-sectional area.
- When a small force is applied to the smaller cylinder, the pressure is transmitted equally to the larger cylinder, resulting in a larger force being exerted.

2. Hydraulic Lift:
- Hydraulic lifts use Pascal's law to lift heavy objects.
- They consist of a small cylinder connected to a larger cylinder by a pipe filled with a fluid.
- When a small force is applied to the small cylinder, it creates a pressure that is transmitted equally to the larger cylinder, resulting in a larger force being exerted to lift the object.

3. Submarine:
- Pascal's law is not directly applicable to submarines. However, the principle of buoyancy and pressure is utilized in the design and operation of submarines.
- Submarines use ballast tanks to control their buoyancy, allowing them to sink or rise in water.
- The pressure inside the submarine changes with depth due to the weight of the water above it, but this is not a direct application of Pascal's law.

Therefore, the correct answer is option B: Submarine because it does not directly rely on Pascal's law.
