Correct Answer Explanation
The pin-code sorting system is an example of Spatial Classification — letters are classified by geographical location (state, district, post office area).
Key Points:
- Pin-code = Postal Index Number — a 6-digit code that classifies addresses by geography.
- Post offices sort letters using pin-codes → this is classification by geographical criteria.
- Similarly, data classified by states, countries, or districts is Spatial Classification.
- This real-world analogy from the activity box reinforces the concept of classification.
