Final answer:
The relationship would be Sinking stream flows towards the sinkhole, and the water drains downward into the bedrock. Option A is correct.
Step-by-step explanation:
The relationship between the sinking stream and the sinkhole as the water drains through the bedrock is that the sinking stream flows toward the sinkhole, and the water drains downward into the bedrock. This is option A.
The water table acts as the boundary between the unsaturated and saturated zones in the ground. As water drains through the bedrock, it seeps from one pore to another, following the topography of the land. The water flow in the bedrock is influenced by geological conditions and can vary, but in the specific scenario of a sinking stream and sinkhole, the water flows toward the sinkhole and drains downward.
