a) dry, hot, and near the equator
b) temperate, northern latitudes, underwater
c) tropical, near the equator, and underwater
d) tropical, at the boundary of two tectonic plates
eliminate

The scenario that most likely describes the ancient environment of the falls is temperate, Northern latitudes, underwater.

Explanation:

The fossil beds of Ohio falls are located near the Ohio river. Fossils ranging to a height of 150m were found on the falls. The fossils discovered belong to the Devonian period.  

A large number of marine fossils have been found in the Falls. These include corals, brachiopods, snails and primitive fish. Since the fossils found in this region are of marine animals it can be confirmed that the falls were underwater during the primitive age.
