The correct answer is: being able to participate in business or trade.
Before the French Revolution, the Second Estate, also known as the French nobility, had some privileges. Besides not being required to pay the taille, a specific kind of tax, they also could participate in business or trade, and they sought to do it by investing not only in trades but also commerce and other ventures. But even with this possibility, their main source of income was the land. The wealthier members of the Second Estate owned large portions of estates and ran them as a business.
