The correct answers are Define a default tag for the "Labels" field, Mark custom fields as required, and Edit the default helper text of the "Description" field.

The Define a default tag for the "Labels" field option is allowed because team-managed project issue layouts let you set default values for certain fields so new issues are prefilled with common tags.

The Mark custom fields as required option is allowed because you can mark custom fields as required on the issue layout to enforce that users provide the necessary information before an issue is created or transitioned.

The Edit the default helper text of the "Description" field option is allowed because the issue layout supports editing helper or placeholder text to guide users on what to enter in the description area.

Move the "Description" field even though the description area only contains "Summary" and "Description" is incorrect because the description area is a fixed part of the issue layout and you cannot reposition the Description independently of that fixed section.

Remove the "Summary" field from the issue form is incorrect because Summary is a required system field and it cannot be removed from the issue form in a team-managed project.
