Sharepoint OnPrem - Using AD Groups in SP

Hello,

have  questions regarding AD Groups in Sharepoint OnPrem 2019:

1. Is there a option to show in field A the Active Directory Group and in a field B the Members of it?
2. Is there a option to use the AD Group from field A as managed property?
3. Are field A oder the resolved Users are able to assign tasks to these users.
   If not is there any other option to assign task to a AD Group?

Thx
