A person migrates to a city for a better job, identify the factor responsible for this migration.

Pull and push factor

The correct answer is Option (1) → Pull and push factor

The person moves to a city because of the pull factor (better job opportunities, higher wages, better facilities). At the same time, conditions in the rural area such as lack of employment or low income act as push factors.

Thus, migration for a better job is best explained by the pull and push factor.
