How should the Architect implement this while using a Salesforce feature?

Cloud Kicks recently started a community for its customers using the Customer Community license type. They have implemented a custom object to store service requests that has a lookup to the account record. The Organization-Wide Default External Access to the service request object is set to Private.

Cloud Kicks wants their customers to be able to see service requests for their account through the community.

However, customers should not see service requests for other accounts.

A . Utilize manual sharing to share the service requests manually when a new community user is added

C . Utilize a Sharing Rule to share service requests to the community user based on their role

community users

Answer: B
