Who may employ foreign nationals to serve as public servants in different government departments?

The correct choice reflects the structure and authority of the Government of the Hong Kong Special Administrative Region (HKSAR) regarding employment practices. Under the Basic Law and related administrative frameworks, it is the responsibility of the HKSAR government to manage public service appointments and personnel matters across its various departments.

This includes the ability to hire foreign nationals for specific positions where their expertise is deemed beneficial for public service duties. The government's overarching authority in these matters is rooted in its function to maintain effective governance and administration in the region.

The other options, while integral to the governance framework, do not possess the specific authority related to employment decisions in public service roles. The Chief Executive's role primarily involves overseeing the government’s execution of policies and leading the administration, but the actual employment of public servants is a broader government function. The Legislative Council's role is more focused on law-making and oversight rather than direct employment actions. The Chief Justice, on the other hand, is concerned with judicial matters and does not engage in the employment of public servants. Thus, the Government of the HKSAR is appropriately positioned as the entity with the authority to make these employment decisions, including hiring foreign nationals for public service.
