Explanation:

For the calendar to be same the year should be a non-leap year and the number of odd days should be 0.

Here, we will calculate the total odd days from 1st Jan of 2007 till 1^st Jan of the year.

2007 – 2008 = 1 odd day
2008 – 2009 = 2 odd days (Total 3 odd days)
2009 – 2010 = 1 odd day (Total 4 odd days)
2010 – 2011 = 1 odd day (Total 5 odd days)
2011 – 2012 = 1 odd day (Total 6 odd days)
2012 – 2013 = 2 odd day (Total 8 odd days)
2013 – 2014 = 1 odd day (Total 9 odd days)
2014 – 2015 = 1 odd day (Total 10 odd days)
2015 – 2016 = 1 odd day (Total 11 odd days)
2016 – 2017 = 2 odd day (Total 13 odd days)
2017 – 2018 = 1 odd day (Total 14 odd days = 0 odd days)

Now, 2018 is also a non-leap year like 2007 and odd days from 2007 till 2018 are 0.

∴ Calendar of 2018 will be same as calendar of 2007.

Hence, option (d).
