The fourth alternative is correct (D).
Norway, Finland and Denmark are among the countries with the highest development index in the world and have a governance structure guaranteeing the Welfare State. In these countries citizens have good jobs and have government guarantees that exist to maintain the quality standard of living for the population.
Poland, however, is not part of this system. Poland is a reminiscent country of the Soviet Union, which was a communist empire that collapsed at the end of the 20th century. Poland and other countries that make up the Soviet Union are low-income countries in Europe that are still recovering from the collapse of the USSR. Despite being part of a communist society, there is no state of social welfare in Poland.
