The Following Passage Contains an Argument That Is Somewhat Complex

The following passage contains an argument that is somewhat complex, either because it makes complicated claims or contains a lot of supplementary information. Identify the best standard-form representation of the argument.
The passage: Without God life [would have no] purpose. For man and the universe would then be simple accidents of chance, thrust into existence for no reason. Without God the universe is the result of a cosmic accident, a chance explosion. There is no reason for which it exists. As for man, he is a freak of nature-a blind product of matter plus time plus chance. Man is just a lump of slime that evolved rationality. As one philosopher has put it: "Human life is mounted upon a subhuman pedestal and must shift for itself alone in the heart of a silent and mindless universe.''
What is true of the universe and of the human race is also true of us as individuals. If God does not exist, then you are just a miscarriage of nature, thrust into a purposeless universe to live a purposeless life.

A) 1) Without God life would have no purpose.
So, Man is just a lump of slime that evolved rationality.
B) 1) Things that exist as a result of random chance do not have a purpose.
2) If God does not exist, then humans exist as a result of random chance. So, if God does not exist, humans do not have a purpose.
C) 1) God does not exist.
2) Without God life would have no purpose. So, life has no purpose.
D) 1) Without God the universe is the result of a cosmic accident and man is a freak of nature.
2) If God does not exist, then you are just a miscarriage of nature, thrust into a purposeless universe to live a purposeless life.
So, without God life would have no purpose.
