Which among the following is a bad conductor of electricity?

Options

A. zinc
B. copper
C. aluminium
D. phosphorus

Explanation

To determine which among the given options is a bad conductor of electricity, we can follow these steps:

### Step 1: Understand the Types of Elements
- There are two main categories of elements: metals and non-metals. Metals are known for their ability to conduct electricity well, while non-metals generally do not conduct electricity effectively.

### Step 2: Identify the Conductivity of Metals
- Metals such as copper, aluminum, and zinc are good conductors of electricity. This means that electricity can easily pass through them.

### Step 3: Identify the Conductivity of Non-Metals
- Non-metals, on the other hand, are typically bad conductors of electricity. They do not allow electricity to flow through them easily.

### Step 4: Analyze the Given Options
- If the options include metals like zinc, copper, and aluminum, these will be good conductors.
- If one of the options is a non-metal, such as phosphorus, it will be a bad conductor of electricity.

### Step 5: Conclusion
- Based on the analysis, the correct answer is that phosphorus is a bad conductor of electricity.

### Final Answer:
- The bad conductor of electricity among the given options is phosphorus.
