What..?
Oh, the trace on the right..? You didn't make it obvious what you were talking about... the screenshot isn't cropped around the subject, and the cursor and crosshairs aren't anywhere near it either...
1. is undesirable because of acute angle.
2. is fine.
3. is also fine but wastes two vias and penetrates the ground pour.
You can augment 2 by adding a triangle or diamond or fillet sort of thing (gussets or teardrops), but this isn't usually important. Sometimes, manufacturers will request that they add such features, though usually around THT pads (where the drill can miss and cut the annular ring apart from the trace).
