The correct answer is: a) Search for employment.
Punjab is a state in northwestern India. It is the most populous state in India, with a population of over 28 million people. The state is known for its fertile land, its agricultural production, and its Sikh culture.
In recent years, Punjab has experienced a significant influx of migrants from other parts of India. The primary reason for this in-migration is the search for employment. Punjab has a strong economy and a low unemployment rate, which has attracted many migrants from other parts of India.
The other options are also possible reasons for in-migration to Punjab, but they are not as common as the search for employment. Education is another important reason for in-migration to Punjab. The state has a number of prestigious universities, which attract students from all over India. Family reunification is also a common reason for in-migration to Punjab. Many people move to Punjab to be with their family members who are already living there. To escape conflict is a less common reason for in-migration to Punjab. However, some people do move to Punjab to escape violence or persecution in their home countries.
