Answer:
Flyers or posters
Explanation:
Communication channels scale from rich to lean. Rich channels are interactive and allow whoever is sending the message and whoever is receiving it to read the nonverbal messages. Examples face to face meeting or a phone call. On the other hand, information on the leanest channels does not have the advantage of immediacy and do not allow for immediate interaction. Examples fliers, social media posts, blogs, reports, and email messages.
