The word ‘epistolary’ means ‘written in the form of letters or correspondence’ and makes no sense here. The word ‘evanescent’ means ‘tending to vanish like vapor’ and is irrelevant here. “Exempt” means free from an obligation or liability imposed on others, and does not 􀁽t here. The word ‘repealed’ means ‘revoke or annul (a law or act of parliament)’ and fits here correctly before the noun ‘law.’ Thus option B is the correct answer.
