Correct Answer: (d) By establishing cottage industry for them
Solution:Gandhi’s socio-economic policy opposes all forms of exploitation. India lives in its villages. Naturally, the development of the country depends on the development of villages. That is why Gandhi stressed on the growth of rural industries such as khadi, handlooms, sericulture, handicrafts, etc. Rural industries are based on family labour and require less amount of capital. Raw materials are available in local and surrounding areas and the goods thus produced is sold in local markets. Therefore, there is no problem with production and market. Gandhi has strongly advocated the development of cottage industries in villages, which will reduce the burden on agriculture. Cottage industry can also work as a good support system for villagers. Thus, all villagers can get employment in their respective villages, which will check the migration to urban areas. According to Gandhi, socioeconomic improvement of untouchables can be brought by establishing cottage industry for them.
