From the eighth century onwards, the subcontinent was dotted with several small towns. These probably emerged from large villages. They usually had a mandapika (or mandi of later times) to which nearby villagers brought their produce to sell. They also had market streets called hatta (haat of later times) lined with shops. Besides, there were streets for different kinds of artisans such as potters, oil pressers, sugar makers, toddy makers, smiths, stonemasons, etc. While some traders lived in the town, others travelled from town to town. Many came from far and near to these towns to buy local articles and sell products of distant places like horses, salt, camphor, saffron, betel nut and spices like pepper.

These are the constitutional instructions or recommendations to the State on legislative, executive and administrative matters.
Statement 3 is incorrect- Directive Principles of State Policy seek to establish social and economic democracy, while Fundamental Rights seek to establish political democracy by giving rights to citizens against arbitrary actions of state.
