Which group of individuals can fill specific high-ranking posts in the Hong Kong government?

The correct choice is rooted in the legal provisions outlined in the Basic Law of the Hong Kong Special Administrative Region. The Basic Law stipulates that high-ranking officials in the Hong Kong government, such as the Chief Executive, executive council members, and other principal officials, must be Chinese citizens who are permanent residents of the region. While British citizens who have settled in Hong Kong might be considered permanent residents, the emphasis remains on individuals who meet the Basic Law's definition of authorities eligible for high-ranking posts.

This option highlights the unique status conferred upon individuals with a historical connection to Hong Kong and British nationality prior to the handover. However, the criteria are strict regarding citizenship and residency, which is why only certain British citizens would qualify under the conditions of permanent residence as set forth in Hong Kong's legal framework.

The other groups mentioned do not fit the criteria established for high-ranking government positions. Foreign diplomats, for instance, are representatives of their nations and cannot hold local government posts due to their diplomatic status. Foreign tourists lack residency and cannot engage in local governance. Permanent residents without the right of abode elsewhere may have legal residency but still may not possess the citizenship qualifications required for these specific roles.
