Answer analysis
Option-by-option breakdown

- ✓
Tokenization
Why this is correct
Tokenization replaces original data with a token that can be mapped back using a secure token vault.

Pseudonymization
Why it's wrong here
Pseudonymization replaces identifiers with pseudonyms, but is usually not reversible without additional information.
- ✗
Bucketing
Why it's wrong here
