Step 1 – Understanding the scenario

The screenshot shows multiple Sensitive Information Types (SITs) in Microsoft Purview, including:

ABA Routing Number (Microsoft-built)

ASP.NET Machine Key (Microsoft-built)

Adatum document patterns (custom, Fingerprint type)

Adatum numbers (custom, Entity type)

Bundled SITs (like All Credential Types, All Full Names)

The question is asking:

Which SITs can you copy to create a new SIT?

Which SITs can you edit directly without copying?

Step 2 – Microsoft rules for SITs

Built-in SITs (published by Microsoft Corporation):

These cannot be edited directly. To modify them, you must create a copy first.

Custom SITs (created in your tenant, e.g., Contoso):

These can be edited directly without making a copy.
