Concept:“Invoke” and “Revoke” are two different words with distinct legal and general meanings, and the correct option must match both definitions accurately.
Explanation:“Invoke” means to call upon or apply something such as a rule, law, or authority to bring about a result.
For example, a court may invoke a particular law to support its decision.
So, “to use the law to achieve something” is the correct sense of Invoke.
“Revoke” means to officially cancel, withdraw, or annul something that was previously granted or allowed.
For instance, a licence or permission can be revoked by the issuing authority.
Thus, “to officially cancel permission or agreement” correctly defines Revoke.
The other options mix up the meanings or introduce unrelated ideas such as repaying debts, ignoring legal procedures, or ushering newness.
Comparing each definition, only option B gives both meanings correctly.
Answer:Option B is the correct answer.
