Correct Answer: 2015

Solution : If the total number of odd days between any year is zero or a multiple of 7, then those years will have the same calendar.
So, Number of odd days in 2010→1
Number of odd days in 2011→1
Number of odd days in 2012→2 (leap year)
Number of odd days in 2013→1
Number of odd days in 2014→1
Number of odd days in 2015→1
Total number of odd days = 1 + 1 + 2 + 1 + 1 + 1 = 7
Since the number of odd days from 2009 to 2015 is 7, 2015 will be the same as the calendar for the year 2009.

Hence, the second option is correct.
