The shape of the shadow does not depend upon _________

Options

A. The shape of the object.
B. The position of the source of light
C. The size of the object
D. The size of the source of light.

Explanation

To solve the question "The shape of the shadow does not depend upon _________", we need to analyze the options given and understand how shadows are formed.

### Step-by-Step Solution:

1. **Understanding Shadows**: Shadows are formed when an object blocks light from a source. The characteristics of the shadow, such as its shape and size, are influenced by various factors.

2. **Analyzing the Options**:
- **Option A: The shape of the object**: The shape of the shadow is directly related to the shape of the object casting it. For example, a round object will cast a round shadow, while a square object will cast a square shadow. Therefore, this option is incorrect.

- **Option B: The position of the source of light**: The position of the light source affects the angle and length of the shadow. For instance, if the light source is directly above the object, the shadow will be shorter and more directly beneath it. If the light source is at an angle, the shadow will be longer and stretched. Thus, this option is also incorrect.

- **Option C: The size of the object**: While the size of the object affects the size of the shadow, it does not affect its shape. A small square will still cast a square shadow, and a large square will cast a larger square shadow. Therefore, this option is correct; the shape of the shadow does not depend on the size of the object.

- **Option D: The size of the source of light**: The size of the light source can affect the sharpness and clarity of the shadow, but it does not change the fundamental shape of the shadow itself. However, it can influence how diffused or sharp the shadow appears. Therefore, this option is incorrect.

3. **Conclusion**: Based on the analysis of the options, the correct answer is that the shape of the shadow does not depend upon the size of the object (Option C).

### Final Answer:
The shape of the shadow does not depend upon **the size of the object**.
