Which of the following best describes the action of rescinding a law?

The action of rescinding a law refers to the process of formally withdrawing or canceling that law, which is accurately described by the term "repealing the law." When a law is rescinded, it is no longer in effect, and this is a direct acknowledgment that the law will not be enforced moving forward.

The other choices present actions related to laws but do not capture the meaning of rescinding. Enforcing a law involves implementing and ensuring compliance with it, which is the opposite of rescinding. Modifying a law means making changes or adjustments to its content or provisions, rather than completely removing it. Expanding the law's scope refers to broadening the application or reach of the existing law, which again does not align with the idea of rescinding.
