I'd vote for "A", the "no auxiliary heating" option.
And I would also wait until the stuff under the foam has fully thawed out
before casting the slab.
ie Water expands volumetrically some double-digit amount (I forget whether
it's 11 or 17%) so if the finished height of the slab is important...well,
you know.
