Answer:

They can use radioactive dating

Explanation:

To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.

DNA acts as the universal genetic material as it is present in all organisms except few. The process related to the DNA molecule is the same in all the organisms.

Since in the given question, the transfer of genes to plants via <em>Agrobacterium</em> and then the expression of the gene in plants shows that the passing of DNA has no barrier as  DNA is the genetic material and the enzyme RNA polymerase recognized the gene which could help produce the mRNA from the gene.

Thus, options-B and D is the correct answer.
