B. metres
C. centimetres
D. millimetres

Explanation

To determine the appropriate unit for measuring the distance between Delhi and Chennai, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Cities**: We need to measure the distance between two major cities, Delhi and Chennai.

2. **Understand the Context**: The distance between two cities is typically quite large, so we need to choose a unit that is suitable for long distances.

3. **List the Units of Length**: The units provided are kilometers, meters, centimeters, and millimeters.

4. **Evaluate the Units**:
- **Kilometers (km)**: This is a larger unit of length, commonly used for measuring distances between cities.
- **Meters (m)**: This is the SI unit of length, but it is more suitable for shorter distances.
- **Centimeters (cm)**: This is a smaller unit, typically used for measuring small lengths.
- **Millimeters (mm)**: This is even smaller and not suitable for measuring distances between cities.

5. **Choose the Most Appropriate Unit**: Given that the distance between Delhi and Chennai is significant, the most appropriate unit to measure this distance is kilometers.

6. **Conclusion**: Therefore, the distance between Delhi and Chennai can be measured in kilometers.

### Final Answer:
The distance between Delhi and Chennai can be measured in **kilometers**.
