Answer
School bag
Reason —
- Butter paper → It is a translucent in nature and allows partial light which forms faint/blurry shadow.
- Glass → It is a transparent object which allows almost all light and hence no shadow forms.
- School bag → A school bag is an opaque object, so it blocks light completely and forms a clear shadow.
- Cellophane → It is also a transparent object so no proper shadow.
