For choice d, the 1982/2000 rulebook (which I prefer), the convoy

fleets in the Irish Sea and the North Sea. However, the French did not
order the convoy. The alternative route with the Russian fleets was
unintended. The English fleet in the English Channel (with the convoy
order) is not part of this alternative route with the Russian fleets.
Since England still "intent" to convoy, the move from Liverpool to
Edinburgh should be via convoy and the two armies are swapped.
Although, you could argue that this is not really according to the
clarification of the 2000 rulebook.
