Question

homophones are words that have exactly the same meaning; have completely opposite meanings; sound the same but have different meanings; are spelled the same but are pronounced differently

Explanation:

To determine the correct option for the definition of homophones, we analyze each choice:

• "have exactly the same meaning" describes synonyms, not homophones.
• "have completely opposite meanings" describes antonyms, not homophones.
• "sound the same but have different meanings" matches the definition of homophones (e.g., "their", "there", "they're").
• "are spelled the same but are pronounced differently" describes heteronyms (or homographs with different pronunciations), not homophones.

Answer:

C. sound the same but have different meanings
