The following table shows data about the types of fossils found in certain sedimentary rock layers from the surface down to the lowest rock layer (Rock Layer E): Rock Layer Fossils Found Surface None A A1, A2, B2, B3 B B1, B2, B3 C C1, C2, D2, E2, E3 D D1, D2, E2, E3 E E1, E2, E3 Based on this fossil record data, between which two rock layers does there appear to have been a mass extinction event? (1 point) Responses C and D C and D A and B A and B D and E D and E B and C

The mass extinction event appears to have occurred between rock layers C and D, as there is a significant change in the types of fossils found between these two layers.
