Correct option is B)

Total number of odd days in first 2000 yeas = 0
Number of odd days in 14 years = 3 x 2 + 11 x 1 = 17 days or  3 odd days
Thus total number of odd days in 2015 = 26 odd days or 5 odd days

Hence, total number of odd days = 5 + 3 = 8 days or 1 odd day
Now, 0 odd days then Sunday, 1 odd day then Monday and so on
Since, 1 odd days hence it is Monday.
