Final answer:
The country with Mt. Hillaby as its highest point is Barbados, a Caribbean island nation. This mountain peaks at about 340 meters above sea level and has a tropical climate.
Step-by-step explanation:
The country whose highest point is Mt. Hillaby is Barbados. Mt. Hillaby is located in the Caribbean and is the highest point on the island, standing at approximately 340 meters (1,115 feet) above sea level. Unlike the other mountains mentioned in the provided information, Mt. Hillaby does not have permanent snow, nor is it an inactive volcano like Mount Kilimanjaro or Mount Kenya. The landscape of Barbados is quite different compared to the high peaks of Africa, such as Mount Kilimanjaro and Mount Kenya, or the Asian Mount Everest, which towers at 29,035 feet as the world's highest peak. Barbados, being an island nation, has a tropical maritime climate with relatively consistent temperatures throughout the year.
