Answer:
The correct answer is letter "B": Chatter groups.
Explanation:
Salesforce is a tool of Customer Relationship Management (CRM) that helps businesses to have a schedule to book appointments and many other different options useful to follow up on the firm's commercial activities.
In Salesforce, chatter groups can be created to share information related to different topics and users can post, comment, and upload files. Chatter groups can be public if access is common for every sales representative of the firm or private when only certain members can make changes.
Thus, if Universal Containers salespeople how coworkers have successfully managed other opportunities with similar products, the sales manager at Universal Containers can create a private chatter group where clerks can share their successful strategies.
