A valid descriptive term can still be the wrong answer.
Germany is a federal state: public responsibilities are divided between the federation and its states. “Federal State Germany” may therefore sound plausible. But the question asks for the full name, including Federal Republic, rather than a description.
The states are parts of this federal country. The plural “federal states” names that level, not an alternative name for Germany as a whole. An individual state and the country as a whole must be distinguished in language.

The other three answers
Read each option as a complete name, not merely a group of familiar words.
Federal State Germany
Federal state accurately describes the state structure. Nevertheless, “Federal State Germany” is not the correct full name.
Federal States Germany
Federal states is the plural term for the constituent states. “Federal States Germany” does not give the country’s full name.
Federal District Germany
Federal District is not the country’s name here. Do not replace Republic with a term that sounds like an administrative unit.
The short name Germany remains correct in everyday use.
The question explicitly asks for the “full name”. That does not make the short form Germany wrong; it simply does not fully answer this particular request. In English, Federal Republic of Germany corresponds to the German state name.
The name alone does not identify every public responsibility. Whether a particular task belongs to the federation, a state or a municipality requires a separate check. Knowing the name does not explain the entire federal system.
Article 20(1) · Basic Law ↗Germany’s full name: Federal Republic of Germany.
Learn the whole phrase and mentally highlight Republic. That word distinguishes the correct answer from the similar-sounding alternatives.
