Tropicals & Tender Perennials: Should I bring it indoors?, 0 by Wintermoor

This is my Brug. versicolor 'Aphrodite'.

It is now 7°C here in Hamburg, and we have the chance of frost tonight.

Should I,

a) bring the plant indoors to overwinter, since I have still more than 35 flower buds hanging on it?

b) cut it back and stick it in the cellar which is very dark?

c) leave it out with a sunshade over it to keep the cold dew from directly hitting the plant.

Help please, and thank you in advance

All the best
