E seems like the obvious answer to me. On Firefly, River Tam would argue that the Bible is “broken” because the Flood was impossible.
I actually found that episode a bit odd because Joss Whedon is a fervent atheist and actually kind of a "New Atheist", which actually fits well with the unsavory aspects of his personality we now know about. I suppose though it's possible he didn't write it. I also found it kind of interesting how Buffy and Angel had all the characters having "Brian Griffin Syndrome", despite the known existence of demons, magic, alternate dimensions, supernatural godlike beings, an afterlife, etc. almost none of the characters seem to actually definitely believe in God. IIRC the only recurring character on either show who was shown to be a Christian was that female LAPD detective on Angel.
Anyway I voted for B.
Riley had beliefs and Willow obviously did.
