What can be a major reason for migration from rural areas to large cities?

Correct answer: Better employment opportunities in cities

Direct answer: A, better employment opportunities in cities are a major reason for rural-to-urban migration. Understand the steps: a rural person may have limited non-farm work or fewer types of jobs nearby. A large city commonly offers work in factories, offices, shops, transport, construction, education, health care, and other services. The possibility of earning an income attracts people; this attraction is called a pull factor. A is correct because employment is a strong and common reason for migration. B is not the best answer because more agricultural land in the rural area can encourage people to stay there. C is incorrect because large cities often have high housing and living expenses, not necessarily lower costs. D is incorrect because better public facilities in villages would reduce the pressure to leave. Memory cue: jobs and opportunities often pull people towards cities.
