According to the Basic Law, who needs to be Chinese citizens and permanent residents of Hong Kong?

The correct choice underscores the requirement that members of the Legislative Council must be Chinese citizens and permanent residents of Hong Kong, as stipulated in the Basic Law. This provision emphasizes the significance of representation and governance within Hong Kong's constitutional framework, ensuring that those in legislative positions have a direct and vested interest in the community they serve, reflecting the principle of "Hong Kong people governing Hong Kong."

For context, while the Chief Executive and members of the Executive Council also have specific eligibility criteria relating to citizenship and residency, the definitive requirement for Legislative Council members is explicitly highlighted in the Basic Law. This establishes a clear standard that reinforces the legislative body's accountability to the residents of Hong Kong. The inclusion of all elected officials may imply a broader scope that isn't explicitly outlined in the Basic Law. Thus, focusing specifically on the Legislative Council clarifies the unique role and expectations placed upon its members within Hong Kong's political structure.
