Answer 1

Answer: (A)

425 million years ago in silurian

The main nitty gritty vascular plant fossils show up in rocks from centre Silurian, around 425 million years prior. The most seasoned of these, including a plant called Aglaophyton, seem to have had directing cells like the hydroids of greeneries.

So, the correct option is '425 million years ago in Silurian'.
