The correct answer is option 4: promotion of cottage industries. Gandhi`s movement of boycotting foreign goods was primarily aimed at promoting and supporting the development of cottage industries within India. Cottage industries refer to small-scale industries that are often based in people`s homes or small workshops. Gandhi believed that by encouraging the production and consumption of local goods, India could become economically self-sufficient and less dependent on foreign imports. This would also create employment opportunities for the rural population and promote a more equitable distribution of wealth. While the boycott did contribute to creating anti-British sentiment, this was not its primary objective. Similarly, while it did indirectly contribute to the goal of full independence, it was not the direct aim of the movement.
