Why is this answer correct?

The Thuringian coat of arms shows the striped lion, banded eight times in red and silver and crowned in gold, on a blue field, surrounded by eight silver stars for the eight Thuringian states; Image 4 shows this coat of arms. The other images show the coats of arms of other states, without these stars.
