The correct answer is C. cottage.
Gandhiji always advocated the cause of cottage industries. He believed that these industries were essential for the economic development of India and that they would help to improve the lives of the poor. He also believed that cottage industries were more sustainable than large-scale industries.
Foreign industries are those that are owned and operated by foreign companies. Big industries are those that are large in scale and have a large number of employees. Native industries are those that are owned and operated by people who are native to a particular country.
Gandhiji believed that foreign industries were not good for India because they exploited the Indian people and took away their jobs. He also believed that big industries were not good for India because they polluted the environment and caused social problems. Gandhiji believed that cottage industries were the best way to develop India because they were sustainable, they did not exploit the people, and they did not pollute the environment.
