b) takes millions of years to form

c) gives evidence of organism’s activity

(i will mark ! )

C) Gives evidence of organism’s activity

Explanation:

Mold are type of fungus that can be found almost anywhere . They can grow on soured foods, furniture , kitchen and hidden places.

Trace fossils are records due to biological(organisms and plants) activities. Trace fossil are impression or imprints made by living organism . The traces could be burrows made by earth worms, footprints by organism and roots traces.   These preserved impression gives evidence of life .

From the Venn diagram  there are two circles with each representing mold and trace fossil, the point where the circles meet depicts both mold and trace fossil comparison.

Base on the question , the Z area which involve only trace fossils gives evidence of organism's activity.
