Concept:Rural-urban migration is the movement of people from villages to towns or cities in search of jobs and better facilities.
Explanation:When industries are established in rural areas, they create local employment opportunities.
Rural dwellers can then find jobs without leaving their home communities.
This reduces the need for the rural working population to travel to urban centres for work.
As more people are absorbed into rural-based industries, the pressure on urban areas decreases.
Consequently, the movement of people away from rural areas to cities is slowed down or reversed.
Therefore, setting up rural industries directly fights rural-urban drift.
Answer:B. Rural-Urban migration.
