Explanation:

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.
Reference: Create a custom sensitive information type
Step 3 - Apply to the exhibit
"Adatum numbers" is published by Contoso (the organization), so it is a custom SIT. This means it can be edited directly.
All SITs, whether built-in or custom, can be copied to form a new SIT.
