Steve Jobs was an unconventional leader. His management style wasn’t the stuff of university textbooks — he wasn’t known for his consultative or consensus building approach. He was a “ high-maintenance co-worker ” who demanded excellence from his staff and was known for his blunt delivery of criticism.　　But it was his sheer genius combined with his ability to articulate his vision and bring staff, investors and customers along on the journey — plus the lessons learned in a major career setback — that made it work. The results: indisputable.　　A “ visionary ” is how he is most often described in relation to Apple, the company he founded with high school buddy Steve Wozniak in 1976. He was effectively fired in 1985, and then returned in 1997 with a renewed sense of purpose.Andwhat a triumphant return it was. According to the LA Times, the market value ofApple’sshares hasgrown from about $US5 billion in 2000 to $US351 billion today, making it one ofthebiggest publiclylisted companies in the US, up there with the likes of Exxon Mobil.　　Whatisthe most suitable title for the passage? A: The Leadership Style in Apple B: Steve Jobs — A Visionary C: Apple: the World’s Leading Mobile Device Company
