Please use the following information to answer the questions below.
Figure 23.1 represents a cross section of the seafloor through a mid-ocean rift valley,with alternating patches of black and white indicating seafloor with reversed magnetic polarities.At the arrow labeled I (the rift valley),the igneous rock of the seafloor is so young that it can be accurately dated using carbon-14 dating.At the arrow labeled III,however,the igneous rock is about 1 million years old,and potassium-40 dating is typically used to date such rocks.Note: The horizontal arrows indicate the direction of seafloor spreading,away from the rift valley.

-If a particular marine organism is fossilized in the sediments immediately overlying the igneous rock at the arrow labeled II,at which other location(s),labeled A-E,would a search be most likely to find more fossils of this organism?
A)B only
B)C only
C)D only
D)B and C
