The correct answers are A. Create a custom-based sharing rule and B. Update the organization-wide defaults.

Here, “custom-based” is most likely referring to a criteria-based sharing rule. UC wants to move from public sharing to a more restrictive model, so the app builder must first update the Organization-Wide Defaults for Accounts. Salesforce OWDs define the default access users have to records they do not own.

Then, to continue giving the Sales team access to all Account records with the Sales record type, the app builder should create a criteria-based sharing rule based on record criteria, such as Record Type. Salesforce criteria-based sharing rules share records based on field values.

C is incorrect because profiles control object permissions, not record-level sharing by record type.

D is incorrect because owner-based sharing rules share records based on record owner, not record type.
