First look for the key inside the shield.
Several answers show a crown. A crown alone is therefore not enough to identify Bremen. Look inside the red shield for the single light-coloured key. The other shields contain lions, a white serrated design or blue and white diamonds.
The official description calls the key’s form Gothic. Silver often appears white or light grey in printed or digital pictures. What matters is the combination of the key and red background, not a metallic shine on the screen.

The other three answers
The other three shields have a different main design.
1
Image 1 combines two blue lions on gold with a white serrated design on red. It lacks the silver key required for Bremen.
2
Image 2 shows three black lions on gold. The crown above them does not turn it into Bremen’s key emblem.
4
Image 4 has a blue-and-white diamond pattern beneath a crown. It has neither the red background nor the silver key.
Several forms of the emblem use the same key.
The rules distinguish large, middle and small forms. The large form adds supporters and a base, the middle form uses the crowned shield, and the small form consists of the key alone. The question shows the middle form. The number 3 belongs only to the exercise.
A study illustration is different from using an official emblem as your own logo. The state offers a separate freely usable design for that purpose. This page preserves the original catalogue graphic; the accompanying AI illustrations do not replace an official coat of arms.

In this picture it is number 3. Look for the key, not just a crown.
