The correct option is A Abrogate
The term "abrogate" means repeal or do away with (a law, right, or formal agreement). For example, "a proposal to abrogate temporarily the right to strike". Hence, Option D is correct. Among the rest of the options, cancel means decide or announce that (a planned event) will not take place, revise means examine and make corrections or alterations to (written or printed matter), obliterate means destroy utterly. These options do not express the intended meaning, hence incorrect.
