Correct Answer: Immigration

Solution : The correct choice is the second option.

Emigration refers to the act of leaving one's own country to settle permanently in another. It involves the departure from a homeland or country of origin to establish a new residence in a different place.

Immigration is the process of individuals entering and settling in a country that is not their native country, thus making it the correct antonym.

The meanings of the other options are as follows:

• Asylum refers to the protection granted by a country to foreign nationals who have left their own country due to fear of persecution. It is a form of protection for refugees.
• Refuge refers to a place or state that provides safety or shelter. In the context of migration, seeking refuge might involve finding a safe place, often in another country, due to danger or persecution.
• The guest term refers to a person who is invited to visit or stay in someone else's home, typically for a short period of time. It is not directly related to the movement of individuals between countries.
