Letʹs say that a hypothetical submersible robot was used to collect samples of sedimentary rock from the sea floor along the section illustrated. The robot moved back and forth along the transect, collecting first from site A, then site III, then site B, then site II, and lastly site D. Assuming that sedimentation has occurred at a constant rate along the transect over the past million years, rearrange the sites mentioned above on the basis of the thickness of the sediments overlying the igneous rock, from thickest to thinnest.

A) SHOOT BUD                                 i) Originated from the many cells, usually superficial

B) SOMATIC EMBRYO                        ii) Polarity is defined as bipolar; both shoot and root poles present
