Step 1: Understanding the Concept:
The United Nations Congress on Crime Prevention and Criminal Justice is a global forum held every five years to discuss issues related to crime prevention, criminal justice, and international cooperation. The question requires arranging four of these congresses in chronological order.

1. London (1960) $\rightarrow$ C
2. Stockholm (1965) $\rightarrow$ B
3. Kyoto (1970) $\rightarrow$ A
4. Milan (1985) $\rightarrow$ D
The correct sequence is C, B, A, D.
