Definitely option b!
Then recycle flaps, slats, speedbrakes and TPI and try again. If the TOCW test is OK, it's probably a fault with the 'interrupter' unit - the thing that makes the horn go 'beep - beep - beep'. Can also be set off if the cabin alt warning input is tits. I know this because I once aborted at 90 KIAS for a TOCW warning once during a 93% FTOT t/o (when the throttles are NOT inside the inhibited range). We came to a halt and discovered that 7 other crews had experienced this snag - but not one had bothered to snag it. W*NKERS!!!! 'twas indeed the cabin alt warning circuit which was causing the spurious fault warning!
