17 - 5 + 1 = 13 years between 2005 and 2017 (inclusive)
10 are normal years and 3 are leap years. As every year has 365 days, or 52 weeks plus a single day, every date will move one day forward the following year (eg. Friday 12 October 2004, will be Saturday 12 October 2005) . As a leap year has 366 days, each date will shift by 2 days.
(10*1)+(3*2) = 16 day shifts between 2005 and 2017 (inclusive), or 2 weeks and 2 days. Which means that 12 October in the year 2017 will be a Sunday.
Answer A.
