Clarify means to

• A. To remove ambiguity
• B. To quote from another source
• C. To make something clearer or easier to understand
• D. To think clearly

Answer: (C)

Clarify means to make something clearer or easier to understand. When you clarify instructions or a statement, you rephrase, explain, or add details so the meaning becomes more unambiguous. This is exactly what clarifying aims to do—present information in a way that removes confusion. Quoting from another source is a separate action (citing), and thinking clearly describes a mental process rather than the act of making something easier to understand. While clarifying often reduces ambiguity, the core idea is simply to present information so it is clear.
