The correct option is C 2001
The year 1990 has 365 days i.e. 1 odd day, year 1991 has 365 days i.e. 1 odd day, year 1992 has 366 days i.e. 2 odd day
Likewise year 1993, 1994, 1995 have 1 odd day each.
The sum of odd days so calculated from year 1990 to 1995 = 1 + 1 + 2 +1 + 1 + 1 + 1 = 7 days
Hence, the year 1996 will have the same calendar as that of the year 1990
