B Correct answer
Explanation

Calendar repeats when total days mod 7 equals 0. From 2005 to 2010: 2005(365)+2006(365)+2007(365)+2008(366-leap)+2009(365)+2010(365) = 365×5 + 366 = 2191 days. 2191 ÷ 7 = 313 with remainder 0. So 2011 starts on the same day as 2005. 2004 differs by 1 day, 2006-2007 differ by more.
