From the choice given I will go with "A".
I just used parallelism on either side of "and"
Though I am not comfortable with any of the choices.

Here's my reasoning:
[spoiler]a. and whether, presuming such life forms having left fossil traces to begin with, those traces can[/spoiler]
Keeps the meaning intact.

b. and wether, if it is presumed that such life forms some fossil traces to begin with, can those traces

Awkward

c. and whther, presuming such life left fossil traces to begin with, can thoses traces

changes the meaning - it is life forms and not just life

d. and, presuming such life forms did leave some fossil traces to begin with, if they can

I am confused as who is "they" referring

e. and, presuming such life forms to have left fossil traces to begin with, if they

I like this answer better but I have same confusion as [D]

What is OA? Would like to know.
