PLZ HELP RN I NEED IT LIKE IN 2 MINS PL Why did Catherine strengthen the nobility after Pugachev’s Rebellion?

The nobility had sided with Pugachev until Catherine promised them more power.
The nobility had been too poor to pay the army without the power Catherine later gave them.
Catherine opposed humanist ideas generally and wanted the nobles to keep their power.
Catherine realized she needed the nobility’s support to keep order in the empire stable.
