Which minister does Lower Saxony not have?

EDITORIAL LEARNING AID

Why is this answer correct?

Foreign policy is exclusively a matter for the federal government (Article 73(1) of the Basic Law), so there is only the Federal Foreign Office and no foreign minister of a federal state. Justice, finance and the interior, by contrast, are separate ministries that every state has.

Only the federal government conducts foreign policy – no state foreign minister.
