Wouldn't the largest subdivision of the United Kingdom just be England? Maybe just change the hint to England instead of the UK because that would be correct? :)
Sorry but nowithstanding that England is not a country.
The south west of England is not a subdivision of England, let alone the largest subdivision of England.
England is divided into counties. The largest subdivision of England is North Yorkshire
The map you show is a reasonable representation of what is considered the regions of England. But the regions, for which there is no formal agreed boundaries, are not subdivisions
