Options

A. Transparent Object
B. Non - Luminous Object
C. Both (a) and (b)
D. Luminous Object

Explanation

**Step-by-Step Solution:**

1. **Understanding the Types of Materials:**
- There are three main categories of materials based on their interaction with light: opaque, transparent, and translucent.
- Opaque materials do not allow any light to pass through them.
- Transparent materials allow light to pass through clearly, enabling a clear image of objects behind them.
- Translucent materials allow some light to pass through but scatter it, resulting in a blurry image.

2. **Defining Cellophane:**
- A sheet of cellophane is a thin, transparent film made from regenerated cellulose.
- It is commonly used for wrapping and packaging due to its clarity and ability to allow light to pass through.

3. **Classifying Cellophane:**
- Since cellophane allows light to pass through and provides a clear view of objects behind it, it is classified as a **transparent material**.
- Additionally, cellophane does not emit its own light; it reflects light instead, which makes it **non-luminous**.

4. **Final Classification:**
- Therefore, a sheet of cellophane is classified as **transparent** and **non-luminous**.
