Who temporarily assumes the duties of the Chief Executive if they are unable to discharge their duties for a short period?

In the context of the Hong Kong Basic Law, if the Chief Executive is temporarily unable to perform their duties, the responsibility for assuming their role does not fall to just one individual but rather could be delegated to various members of the government. The Basic Law outlines mechanisms for the smooth functioning of government during such absences.

When the Chief Executive is unable to carry out their responsibilities, it is typically the Administrative Secretary, Financial Secretary, or the Secretary of Justice who can temporarily assume the Chief Executive's duties. This ensures that the administration can continue to function effectively. Since all these officials are high-ranking members of the government, they all possess the necessary expertise and authority to fulfill these duties.

Choosing "All of the above" reflects an accurate understanding of the distribution of power and responsibilities within the Hong Kong government. Each of these positions is significant, and their ability to step in emphasizes a system of checks and balances designed to maintain governance in the absence of the Chief Executive.
