Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Catalog Client Script (OnChange)
Why this is correct
OnChange client scripts trigger when a specific variable's value changes.
- ✗
Catalog UI Policy (Run scripts)
Why it's wrong here
While UI policies can run scripts, OnChange client scripts are designed specifically for reacting to value changes on a single variable.

Business Rule (Display)
Why it's wrong here
Display business rules run when records load on the server, not when catalog variables change on the client.

Catalog Server Script
Why it's wrong here
Catalog Server Script is not a standard standalone client-interacting script type.
