Hint 2 of 2
Check both the shape and the little drawings on each piece, and turn a piece only if it still fits.
Show solution
Approach: match the empty gap to the piece that fits it
  1. Look at the hole in the picture and notice its shape and the marks that belong there.
  2. Hold each answer piece up to the gap and see which one matches perfectly.
  3. Only piece A fits both the shape and the marks, so the answer is A.
