I always go with option (a), when I have reason to believe my players don't already know how I stand on the subject.It's been over 15 years since gods cutting off access to spells has been part of the current PHB or DMG. It is therefore emphatically not part of the default and is therefore either (a) something the DM needs to explicitly pitch in advance, (b) hidden well within the small print of the setting material (which the players may not have read), or (c) the DM changing the contract. It has not been a part of the default social contract since 3.5 had paladins falling - and even that wasn't clerics losing spells.
