Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Run the SQL Tuning Advisor
Why it's wrong here
The advisor might recommend a profile, but setting preferences is cleaner for maintenance.

Modify the init.ora parameter
Why it's wrong here
Global parameters are not the right tool for local stats issues.

Use DBMS_STATS.SET_TABLE_PREFS
Why this is correct
Preferences allow granular control over how stats are gathered for a specific object.
