Option A is near impossible imo. Haschqalth has states his and Yhwach's dislike of drawn out conflict, so he wouldn't want to 'prove himself' in battle by beatin shunsui without medalizing his bankai. Quincies have been shown to be sneaky, efficient and ruthless in battle. I think this is an excuse to substantially shorten battle length as seen this arc with the quincies as I am pretty sure Kubo's editors are rushing him through this 'final' arc.
