The correct option is C Sunday
Given, 26 January 1995 fell on a Thursday and we have to find the day on 26th Jan 1986.
Between, 26 Jan 1986 and 26 Jan 1995, we have 2 leap years (1988 and 1992) and 7 ordinary years.
Therefore, number of odd days = 2 X 2 + 7 X 1 = 11 days or 1 week and 4 odd days
So, the day on 26 Jan 1985 is 4 days back from Thursday i.e., Sunday.
Hence, option (C) is the correct answer.
