How would you address the maker1`s issue with data access?

Answer options:

A.Change the maker’s role from Microsoft Dataverse User to Environment Maker
B.Change the maker’s role from System Administrator to Environment Maker
C.Change the maker’s role from Environment Maker to Microsoft Dataverse User
D.Change the maker’s role from Environment Maker to System Customizer
E.Change the maker’s role from Knowledge Manager to System Administrator

Correct Answer: D 
Microsoft Dataverse environment with the provisioned database provides several predefined security roles: System Administrator — has full permission to the environment, including managing the security roles.
Environment Maker — can create new resources, like apps, flows, connections, gateways, share the apps with the users in an organization. But this role does not have privileges to access the environment’s data.
System Customizer — has full permissions to customize the environment, but they can only view records for the tables they create.
Basic User — can run an app in the environment and access the data they create in non-custom tables.
Delegate — can impersonate another user’s role.
If the maker1 can create a form and cannot access the data, she has the Environment Maker security role. To get access to the data, she needs to have the System Customizer role.
All other options are incorrect.
