Step 1: Context.
In 18th century Bengal, landlords had to maintain regular services from artisans like blacksmiths, carpenters, and weavers. For these services, they made payments in cash or kind.
Step 2: The Jajmani system.
This arrangement was called the Jajmani system, in which artisans provided hereditary services to landlords or peasants in exchange for payment or maintenance. It was essentially a patron-client system.
Step 3: Elimination.
- (A) Miras: Refers to hereditary ownership of land, not artisan service.
- (C) Watan: Refers to hereditary offices/rights, not cash payment for services.
- (D) None of these: Incorrect, because the system had a name — Jajmani.
Step 4: Conclusion.
Hence, the correct answer is Jajmani system.
