First the stripes, then the green ornament.
The constitution describes a shield divided nine times. Nine divisions produce ten stripes: five black and five gold. You do not need to master heraldic terminology to recognise the pattern in the original graphic.
The green rue crown lies across the stripes. From your viewpoint, it runs from the upper left to the lower right. It is a diagonal ornament with leaf-like projections inside the shield, rather than a crown sitting on top of it.
The other three answers
The other three images use different main motifs.
1
Image 1 shows blue and white diamonds beneath a crown. A diamond pattern is different from the green rue crown over black-and-gold stripes.
2
Image 2 shows a black bear on a pale background with a crown above. Sachsen’s shield does not contain a bear.
3
Image 3 shows a white horse on a red background. It lacks both the black-and-gold stripes and the green rue crown.
Coat-of-arms colours are not automatically flag colours.
Sachsen’s state colours are white and green. Black and gold belong to the striped shield. This distinction also helps with the separate question about the state flag.
Number 4 applies to the order shown here. The unchanged catalogue graphic appears in the quiz; the editorial AI images show only a fictional study situation and materials. They do not replace an official coat of arms.
Article 2(3) · Constitution of Sachsen ↗Black-and-gold stripes + green rue crown → Sachsen.
In this image sequence, that is image 4. Remember the flag colours separately: white and green.
