Answer:
Friendly.
Explanation:
The word that best completes the statement is 'friendly' as only the friendly audience can be sympathetic as they understand, analyze and respond effectively to the speaker's thoughts, experiences, and ideas. The other options imply a negative tone as the passive audience merely observes without any reaction or response, a neutral audience includes those who are unable to reach a decision, and a hostile audience is antagonistic and offensive towards the speaker and thus, could not display sympathy to the speaker. Thus, this makes us conclude that a friendly audience is likely to be more sympathetic.
