If the absolute difference between imports and exports are ranked in ascending order, which year gets 4th rank?

The absolute difference year wise is:-
2002 = 275-112.5 = 162.5
2003 = 250-150 = 100
2004 = 225-150 = 75
2005 = 225-200 = 25
2006 = 275-175 = 100
2007 = 200-200 = 0
2008 = 275-175 = 100
2009 = 200-175 = 25
2010 = 262.5-200 = 62.5
2011 = 250-175 = 75
Thus, in ascending they'll be 2007, 2009/2005, 2005/2009, 2010, 2006/2008/2003,  2006/2008/2003, 2006/2008/2003, 2002
Thus, year 2010 will rank 4th.
Hence, option A is the correct answer.
