Cloud Kicks has a Public Read Only sharing model for Opportunities. A sales rep can edit some opportunities associated with accounts they own but cannot edit others.

Account Teams:

Definition: Account Teams allow multiple users to have access to an account and its related records, such as opportunities, cases, and contacts.

Access Levels: Team members can have varying levels of access (Read Only, Read/Write) to the account and related records.

Scenario Analysis:

Editable Opportunities: The sales rep can edit opportunities where they are a member of the Account Team with Read/Write access on Opportunities.

Non-Editable Opportunities: For opportunities where they are not on the Account Team or have Read Only access, they cannot edit those opportunities, even if they own the account.

Why Other Options Are Less Suitable:

Option A: Ownership of the account does not grant edit access to all related opportunities if the opportunities are owned by other users and sharing settings are restrictive.

Option B: Sharing rules for managers would not directly impact a sales rep's ability to edit opportunities unless they are part of that public group, which isn't indicated in the scenario.

By being a member of an Account Team with Read/Write access on Opportunities, the sales rep gains the ability to edit certain opportunities associated with accounts they own.
