The correct option is A Business leaders were worried with the queen ascending the throne as she refused to acknowledge the constitution.
In 1887, the US established a naval port in Pearl Harbor, Hawaii under the new constitution. Americans investors invested in the sugar plantations and the sugar imports to America also increased as a result. However, in 1891, Liliuokalani, sister of the late emperor Kalakaua ascended the throne and refused to accept the constitution of 1887 and as a result of this in 1893, Stanford B. Dole of the revolutionary "committee of safety" launched a coup against the queen and Hawaii became the protectorate of US.
