The accompanying map shows the Atlantic Ocean divided into zones A, B, C, and D. The Mid-Atlantic Ridge is located between zones B and C.

Which graph best represents the geologic age of the surface bedrock on the ocean bottom?
A.

B.

C.

D.

It is not possible to determine the best graph to represent the geologic age of the surface bedrock on the ocean bottom based solely on the given information and map. The map shows the location of the Mid-Atlantic Ridge and the division of the Atlantic Ocean into zones, but does not provide specific information about the age of the bedrock in each zone. Additional geological data and research would be necessary to create an accurate graph of the geologic age of the ocean floor.
