Depends on the upbringing. I'd say A and B - Wilhelm II was a product of his time, and you can't take away that entirely. He won't turn into the Dalai Llama, no matter who teaches him. At the same time, a different upbringing would have given him a better understanding of diplomacy and publicity, which could havve averted a fair number of the blunders that led to Germany's diplomatic isolation in the years prior to WWI. That, in turn, woulod have stood a decent chance of stopping the sense of panic in the General staff about germanyÄ's untenable strategic position and thus curb their willingness to go to war in 1914. Not to menntion give Wilhelm himself pause before he signed away his political initiative to austria-Hungary.
