An alloy used in making heating elements for electric heating devices is

Options

A. solder
B. alloy steel
C. nichrome
D. German silver

Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for an alloy that is used in making heating elements for electric heating devices.

2. **Defining an Alloy**: An alloy is a mixture of two or more metals, or a metal and a non-metal, that has properties different from those of its components.

3. **Identifying Common Alloys**: There are various alloys used for different purposes. In the context of heating elements, we need to think about alloys that have good electrical resistance and can withstand high temperatures.

4. **Recognizing Nichrome**: One of the most commonly used alloys for heating elements is Nichrome. Nichrome is primarily composed of nickel and chromium, and it is known for its high resistance and ability to withstand high temperatures.

5. **Application of Nichrome**: Nichrome is used in various electric heating devices, such as toasters, electric ovens, and hair dryers, because it can efficiently convert electrical energy into heat.

6. **Conclusion**: Therefore, the alloy used in making heating elements for electric heating devices is Nichrome.

**Final Answer**: Nichrome.
