Quizplus · Accepted Answer

Caves are typically formed by water dissolving soluble rocks such as limestone, dolomite, or gypsum. This dissolution occurs most commonly just below the water table, where groundwater can flow and react with the rock to dissolve it. Therefore, option B, just below the water table, is the best choice.
