Refer to the table below.
Carbon-14 was used to label carbon dioxide, which was then exposed to plant cells grown in culture. Cells were then broken open and the radioactive compounds extracted and chromatographed as described in the animated tutorial. The experiment was repeated using varying exposure times and the intensities of spots on the final radiochromatogram were determined. Based on these results, what can be deduced about the pathway sequence of these compounds?
A.
B.
C.
D.
