Identify the odd one out with respect to casting a clear shadow in bright sunlight:
  1. Cardboard sheet
  2. Iron plate
  3. Clean clear glass pane
  4. Thick plastic tray

Solution

Clean clear glass is transparent and lets light pass through without blocking it, so it does not form a dark shadow like opaque materials.
