Which coat of arms belongs to the federal state of Hesse?

Why is this answer correct?

The Hessian coat of arms shows the red-and-white striped lion with a golden crown – the "colourful lion". Image 1 shows this coat of arms; the other images show coats of arms of other federal states and are therefore wrong.

Hesse: the colourful lion, striped red and white and crowned in gold.
