B. Saturday

C. Friday

D. Wednesday

Answer: Option C

Solution(By Examveda Team)

On 31st December, 2005 it was Saturday.
Number of odd days from the year 2006 to the year 2009 = (1 + 1 + 2 + 1) = 5 days.
∴ On 31st December 2009, it was Thursday.
Thus, on 1st Jan, 2010 it is Friday.

    In ordinary year there is 52 weeks and 1 day extra so that day is odd day for ordinary year ......for leap year 52 weeks and 2 odd day means 2 extra day.
