The correct options are
B Helps in Expansion of trade
C Helps in modernising agriculture
D Helps to overcome poverty
When the products manufactured in the manufacturing industries find takers in the international market, the expansion of trade happens. This will bring in more foreign exchange to the country. Manufacturing industries also modernise agriculture by selling to farmers, products such as irrigation pumps, fertilisers, insecticides, pesticides, plastic and PVC pipes. The government has established many public sector undertakings and joint sector ventures in India.
