Final answer:
The oldest of the seven coalescent volcanoes of Ancient Maui Nui is (a) Lana'i.
Therefore, correct answer is a) Lana'i.
Step-by-step explanation:
Lana'i, one of the Hawaiian Islands, holds the distinction of being the oldest among the seven coalescent volcanoes that formed Ancient Maui Nui. This geological history contributes to the unique landscape and diverse ecosystems found on the island.
The formation of Ancient Maui Nui involves the coalescence of multiple volcanic islands due to their overlapping eruptions and subsequent merging over time. Lana'i, as the oldest component, represents a significant stage in this geological process. The dynamic volcanic activity in the region has played a crucial role in shaping the topography and biodiversity of Ancient Maui Nui.
Therefore, correct answer is a) Lana'i.
