D. Precambrian Supereon.
The Precambrian Supereon represents the vast majority of Earth's history, encompassing about 88% to 90% of geological time. It spans from the formation of Earth about 4.6 billion years ago to the start of the Cambrian Period, about 541 million years ago. The Precambrian Supereon is divided into three eons: the Hadean, Archean, and Proterozoic.
