The two recommended solutions for the app builder to give the users appropriate access are creating a criteria based sharing rule to all opportunities with the sales operations public group and adding a permission set with
'View All" and 'Modify All'' opportunity permissions enabled. A criteria based sharing rule can grant read and write access to all opportunities that meet certain criteria to a specified group of users. A permission set can grant additional object-level permissions to users without changing their profiles. Option B is incorrect because adding a manual share for all opportunities with each user on the sales operations team is not scalable or maintainable. Option D is incorrect because creating a criteria-based sharing rule to share all opportunities with the sales operations private group is redundant, as private groups are used to manually share records with individual users or other groups.

To deploy a new account detail page layout from sandbox to production, an app builder should include three components in the change set:
Detail page layout: The page layout defines the arrangement of fields, buttons, related lists, and other components on a record detail or edit page. It also controls which fields are required or read-only for users. Source Custom fields: Custom fields are fields that are created by users to store additional information on standard or custom objects. Custom fields can have different data types, such as text, number, date, picklist, etc. Source Custom actions: Custom actions are actions that are created by users to extend the functionality of standard or custom objects. Custom actions can be global or object-specific, and they can invoke different tools such as Lightning components, Visualforce pages, flows, etc. [Source]

The two considerations that should be made are: The Star records are all required to have an existing value in their Galaxy field. This is a prerequisite for converting a lookup relationship to a master-detail relationship. A lookup relationship is an optional relationship that links two objects together, but does not enforce referential integrity or cascade delete. A master-detail relationship is a required relationship that links two objects together and enforces referential integrity and cascade delete. To convert a lookup relationship to a master-detail relationship, all child records must have a value in their lookup field that references an existing parent record. The Galaxy object has fewer than two existing master-detail relationships. This is another prerequisite for converting a lookup relationship to a master-detail relationship. An object can have up to two master-detail relationships with other objects and can act as both the parent and child in different relationships.
To convert a lookup relationship to a master-detail relationship, the parent object must have fewer than two existing master-detail relationships with other objects. The Galaxy object is required to contain existing roll-up summary fields is not a valid consideration, as it is not related to converting a lookup relationship to a master-detail relationship.
