What follows the analogy norway : norwegians in a similar format?

The analogy aims to establish a relationship between a country and the people who are from that country. The correct answer, which pairs El Salvador with Salvadorans, provides a direct connection similar to Norway and Norwegians.

In this case, each country is followed by the demonym that describes the citizens or natives of that country. Just as people from Norway are called Norwegians, people from El Salvador are referred to as Salvadorans, maintaining the same grammatical structure and concept.

The other options do not fit this pattern clearly. Papua New Guinea's correct demonym is Papua New Guineans, which diverges from the choice given. Japan refers to a broader ethnic classification with Asians, which doesn’t denote the specific people from Japan. Similarly, while those from Israel may identify as Jews, this term isn't exclusive to the nationality as it also includes a broad religious and cultural identification. Thus, the pair of El Salvador and Salvadorans best mirrors the relationship presented in the original analogy.
