Final answer:
The size of the shadow depends on the size of the object relative to the light source.
Step-by-step explanation:
The correct statement is B: smaller the object, bigger its shadow.
When an object is placed between a light source and a wall, it casts a shadow. The size of the shadow depends on the size of the object relative to the light source. If the object is smaller, the shadow it casts on the wall will be larger. Conversely, if the object is larger, the shadow will be smaller.
For example, if you hold a small toy car between a lamp and a wall, the shadow it creates on the wall will be bigger compared to the toy car itself.
