Hint 2 of 2

Show solution
Approach: match the cyclic order of letters around the umbrella
  1. Read the letters around the top of the umbrella in order: K, A, N, G, A, R, O, O.
  2. On a side view the visible panels must keep that same neighbouring order.
  3. Only picture A shows the letters in the correct order and orientation around the rim.
