<h3>d) step migration across member states to a final destination.</h3>
Explanation:
Step migration is a pattern of migration which was first propounded by Ernst Georg Ravenstein in 1885. He observed that modern migration involves step by step pattern where migrants from rural places slowly moves closer and closer to urban places.
In modern times, transnational migration mostly occurs through step migration. For instance, international students are granted citizenship in the countries where they study if they prove to be skillful and productive. It is a step by step process.
Similarly, permanent citizenship is granted to migrants if they prove to have settled and worked in a member state country of a particular region or union. Here, the refugee entered the European Union in Italy and was housed in Germany for sometime. This shows that he/she has been living in Germany for sometime and therefore, gets asylum and citizenship in Sweden as these countries all belong to the same union and region.
