The diameter of the circle is 3 cm.AB(horizontally drawn) and MN(vertically drawn) are two diameters such that MN is perpendicular to AB.In addition,CG is perpendicular to AB such that AE : EB=1 : 2,and DF is perpendicular to MN such that NL : LM=1 : 2.C,G,D and F are on the circumference of the circle.CG is drawn to the left of MN and DF is drawn below AB.The length of DH in cm is
(a) 2*sqrt(2)-1
(b) (2*sqrt(2)-1)/2
(c) (3*sqrt(2)-1)/2
(d) (2*sqrt(2)-1)/3
