The Hong Kong National Security Law (NSL), imposed in 2020, primarily impacts the future viability of which governance principle?

💡 Explanation:

The National Security Law (NSL) was imposed by Beijing in 2020 and significantly expanded the central government's power in Hong Kong. Critics and analysts widely view this law as fundamentally undermining the 'One Country, Two Systems' principle, which guaranteed Hong Kong a high degree of autonomy and its own legal and political systems for 50 years after the 1997 handover.
