Hint 1 of 2
The three poles each carry the same markers at fixed spots - the windmill keeps those.

Hint 2 of 2
Each pole becomes one straight line through the centre, so its two ends keep their original markers.
Show solution
Approach: match the three poles' end-markers to a windmill
- Each pole is one line through the centre, with its two given end-markers preserved.
- Three poles make six arms with three matching marker pairs.
- Only option B uses exactly those three pole patterns.
- So George makes windmill B.
