Hint 2 of 2
The post-tops and the holes keep their pattern but the whole strip is turned a quarter-turn — match that exact pattern.
Show solution
Approach: rotate the upright fence a quarter turn and match
  1. When the fence falls it turns a quarter turn, so the pointed tops now face sideways and the row of holes keeps its spacing.
  2. Only one picture shows the post shapes and hole pattern in the orientation you get from tipping the fence over.
  3. That picture is C.
