The correct answer is: Maharashtra, Karnataka, Kerala.
Goa is a small state in western India that is known for its beautiful beaches, laid-back lifestyle, and Portuguese colonial architecture. It is a popular tourist destination, and attracts a significant number of migrants from neighboring states. The three states that send the most migrants to Goa are Maharashtra, Karnataka, and Kerala.
Maharashtra is the most populous state in India, and is located to the north of Goa. It is a major economic and industrial center, and many people from Maharashtra move to Goa in search of work. Karnataka is located to the east of Goa, and is a major agricultural and industrial state. Many people from Karnataka move to Goa in search of work or a better quality of life. Kerala is located to the south of Goa, and is a state with a high literacy rate and a strong economy. Many people from Kerala move to Goa in search of work or a better quality of life.
The other three options are incorrect because they are not neighboring states of Goa. Gujarat is located to the north-west of Goa, Rajasthan is located to the north-east of Goa, and Punjab is located to the north of Goa.
