___________ is a process in which an electrolyte decomposes into its constituents when electric current is passed through it.

Options

A. Electrolysis
B. LED
C. Electroplating
D. All of them

Answer

**Step-by-Step Solution:**

1. **Understanding the Question:**
The question asks for a process in which an electrolyte decomposes into its constituents when electric current is passed through it.

2. **Identifying Key Terms:**
- **Electrolyte:** A substance that conducts electricity when dissolved in water or molten, allowing it to decompose.
- **Decompose:** To break down into simpler constituents.
- **Electric Current:** The flow of electric charge.

3. **Analyzing the Options:**
The options provided include:
- LED (Light Emitting Diode)
- Electroplating
- Electrolysis

4. **Evaluating Each Option:**
- **LED:** This is a type of light source and does not relate to the decomposition of electrolytes.
- **Electroplating:** This process involves depositing one metal onto another using electric current, but it does not specifically refer to the decomposition of an electrolyte.
- **Electrolysis:** This is the process where an ionic compound is decomposed into its elements by passing a direct current through it.

5. **Conclusion:**
The correct answer is **Electrolysis**. It is the process in which an electrolyte decomposes into its constituents when electric current is passed through it.

6. **Definition of Electrolysis:**
Electrolysis is defined as the process of decomposing an ionic compound into its elements by passing a direct current through it in a fluid form.

7. **Summary:**
Therefore, the answer to the question is **Electrolysis**.
