Pascal's law states that a pressure change applied to an enclosed incompressible fluid is transmitted undiminished throughout the fluid and to the container walls. When a toothpaste tube is squeezed, the applied pressure is transmitted through the paste and pushes it out through the opening. Thus both Assertion A and Reason R are true, and R correctly explains A. Hence option B follows.
