The correct answer is A. The eon of the geological time scale that means "visible life" is the Phanerozoic.

Explanation:

The Phanerozoic Aeon is a division of the geological time scale that extends from 542.0 ± 1.0 million years to the present day. It replaces the Precambrian, which covers the time remaining since the formation of the Earth.

Long before this eon life on Earth already existed, however it is during this period when living organisms already take complex forms, evolve and diversify widely.
