Which of the following is a true statement?

Options

A. Plastic is soluble in water
B. Plastic is not a polymer
C. Rayon is made from cellulose
D. All plastics are fire resistant

Answer

To determine which of the given statements is true, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Evaluate the First Statement: "Plastic is soluble in water."**
- **Analysis:** Plastics are generally known to be insoluble in water. They do not dissolve in water, which makes this statement false.
- **Conclusion:** This statement is **false**.

2. **Evaluate the Second Statement: "Plastic is not a polymer."**
- **Analysis:** Plastics are indeed polymers. They are made up of long chains of repeating molecular units. Therefore, this statement is incorrect.
- **Conclusion:** This statement is **false**.

3. **Evaluate the Third Statement: "Rayon is made from cellulose."**
- **Analysis:** Rayon is a synthetic fiber that is made from cellulose, which is derived from wood pulp. This statement is accurate.
- **Conclusion:** This statement is **true**.

4. **Evaluate the Fourth Statement: "All plastics are fire resistant."**
- **Analysis:** While some plastics, like melamine, are fire resistant, others, such as polythene, are not. Polythene can melt when exposed to high temperatures. Therefore, this statement is misleading.
- **Conclusion:** This statement is **false**.

### Final Answer:
The true statement among the options provided is: **"Rayon is made from cellulose."**
