The correct answer is:
discrimination of citizens by the state.
Ungleichbehandlung der Bürger und Bürgerinnen durch den Staat.
Independent study resource, not a BAMF website. Translations are study aids; the exam is in German.
Quick explanation
The state may not arbitrarily treat citizens unequally.
Why is this correct?
The equality principle binds state action, while petitions and the freedoms of expression and assembly are protected rights.
Background
Article 3 of the Basic Law states: “All persons shall be equal before the law.” Nobody may be disadvantaged because of their sex, parentage, language, origin, faith, political opinions or a disability. The state must treat everyone equally – for example at public offices, at school or in court. Unequal treatment by the state is therefore forbidden.
Why are the other answers wrong?
Freedom of expression (Article 5), petitions (Article 17) and freedom of assembly (Article 8) are fundamental rights and therefore explicitly allowed. With a petition, you can address requests or complaints in writing to authorities or parliaments.
Memory tip
Three answers are fundamental rights – only unequal treatment is forbidden.
Legal basis: Art. 3 Basic Law (GG) ↗
