EDITORIAL LEARNING AID

Why is this answer correct?

The state coat of arms of Saxony-Anhalt shows the Saxon rue crown and the Prussian eagle in the upper field and, below, the striding black bear on a red wall for Anhalt; Image 4 shows this coat of arms. The other images show the coats of arms of other states without these three symbols.

Rue crown, eagle, bear: Saxony-Anhalt has all three.
