The correct answer is: A. M.S. Dhoni
M.S. Dhoni was named the Indian cricketer of the year 2008 by Wisden. He was the first Indian wicket-keeper to score a double century in Test cricket, and he also led India to victory in the 2007 ICC World Twenty20.
Virendra Sehwag was the leading run-scorer in Test cricket in 2008, but he was not named the Indian cricketer of the year by Wisden. This is because Sehwag was not as successful in limited-overs cricket as Dhoni was.
Anil Kumble was the leading wicket-taker in Test cricket in 2008, but he was not named the Indian cricketer of the year by Wisden. This is because Kumble was not as successful in limited-overs cricket as Dhoni was.
Saurav Ganguly was the captain of the Indian cricket team from 2000 to 2005, but he was not named the Indian cricketer of the year by Wisden in 2008. This is because Ganguly was not as successful in 2008 as Dhoni was.
