Which of the following statements best describes the trajectory of North Korea's nuclear and missile programs?

• A. It has remained static with no new capabilities.
• B. It has expanded rapidly.
• C. It has never pursued missiles.
• D. It has shifted focus to cyber warfare exclusively.

Answer: (B)

North Korea’s nuclear and missile efforts show rapid growth in capability over time. The program has moved from testing basic systems to fielding longer-range, more sophisticated missiles and improving the reliability and survivability of launches, with an increasing pace of tests and diversification of missile types and launch platforms. This pattern demonstrates expansion and advancement rather than stasis.

The other options don’t fit because the program has not stayed static—the capabilities and testing have continued to evolve. It has clearly pursued missiles, not never pursued them, and while cyber capabilities exist, the dominant trend of the program is not an exclusive shift to cyber warfare.
