The correct answer is (c) Norway.
India and Norway signed a social security agreement in June 2012. The agreement aims to protect the social security rights of workers who move between the two countries. It covers areas such as pension, sickness benefits, unemployment benefits, and family benefits.
The agreement is based on the principle of totalization, which means that each country will take into account the periods of insurance or employment that the worker has completed in the other country. This will ensure that the worker does not lose out on any social security benefits.
The agreement is also based on the principle of reciprocity, which means that the rights and obligations of the two countries are equal. This means that Norwegian workers who move to India will have the same social security rights as Indian workers who move to Norway.
The agreement is a significant step in strengthening the relationship between India and Norway. It will help to promote trade and investment between the two countries and will make it easier for people to move between them.
Estonia, Finland, and Sweden are all Nordic countries that have signed social security agreements with India. However, the agreement with Norway is the most recent and comprehensive.
