Hint 2 of 2
Flip the front picture left-to-right and match the tall/short order of the three blocks to a choice.
Show solution

- Viewing the blocks from behind reverses their left-right order while keeping every height unchanged.
- Mirror the given front arrangement horizontally.
- The mirrored picture matches choice B.
- So from behind the blocks look like B.
