Final Answer :
A
Explanation :
Submerged ridges in the Philippine Sea were primarily formed by back-arc basins, which are geological features that occur behind a volcanic arc and are associated with subduction zones. These basins form as a result of the stretching and thinning of the Earth's crust, leading to the creation of new oceanic crust and often resulting in the formation of ridges and other underwater topographical features.
