Find the region first, then the small outline.
Start with the whole map of Germany. Berlin is neither in the southwest nor on the coast. Look further right in the upper part of the map for the small dark area within a larger state outline.
Number 4 is outside that area. Its connecting line leads upward to the target. Labels for small states need space beyond their outlines. A digit printed beside another state therefore does not automatically label that neighbouring state.

The other three answers
The other arrows point to other small states.
1
Arrow 1 leads to Bremen in the northwest. Berlin lies much further east. A small marked area alone is therefore not a sufficient identifying feature.
2
Arrow 2 points to Saarland in the southwest. It is in a different part of the map of Germany from Berlin.
3
Arrow 3 points to Hamburg in the north. Hamburg is also a city-state, but it is not Berlin, which lies further east and south.
Distinguish geographical position from political membership.
Being surrounded by Brandenburg does not make Berlin a district of that state. An enclosed area can politically be a separate federal state. That combination is useful for recognising it here.
Number 4 belongs only to this question’s illustration. It is not a general official code for Berlin. The map is a simplified learning overview; the additional AI photographs are fictional everyday scenes, not geographical evidence.
Berlin and its surroundings · State of Brandenburg · Geography ↗Berlin: small area in the northeast, number 4 here.
Check the arrowhead and recognise Brandenburg as the surrounding state.
