To determine the correct answer to the question, "Effective listeners know they must?" you can follow these steps:

1. Read the options provided: "a. enunciate each and every word," "b. focus attention on the speaker," and "c. use the appropriate speaking volume."

2. Understand the question: The question is asking what effective listeners need to do.

3. Analyze each option:
- Option a, "enunciate each and every word," is related to how the speaker expresses themselves, not how the listener needs to behave.
- Option b, "focus attention on the speaker," is directly related to being an effective listener because it highlights the importance of concentrating and giving their full attention to the speaker.
- Option c, "use the appropriate speaking volume," is again related to how speakers should adjust their volume, not how listeners should behave.

Therefore, the correct answer is b. Effective listeners know they must focus attention on the speaker.
