Why is this answer correct?

The coat of arms of Schleswig-Holstein is split: on the right two blue lions on gold for Schleswig, on the left the silver nettle leaf on red for Holstein; Image 3 shows this coat of arms. The other images show the coats of arms of other federal states, without a nettle leaf.

Two blue lions and a nettle leaf: Schleswig-Holstein.
