Correct Option: B

The hydraulic brake is an arrangement of braking mechanism which uses brake fluid, typically containing glycol ethers or diethylene glycol, to transfer pressure from the controlling mechanism to the braking mechanism. It works on the principle of Pascal’s law which states that “pressure at a point in a fluid is equal in all directions in space”. When pressure is applied on a fluid it travels equally in all directions so that uniform braking action is applied on all wheels.
