**ashutosh**, Sunday, May 26, 2013 at 4:25amMake a line segment OE. Since OE=OB, angle OEB = angle OBE. This implies that angle FEC = 90 - angle OEB = 90 - angle OBE = angle DFB = angle EFC.

Thus angle FEC = angle EFC. Thus EC = CF = 110.

Now in right angle triangle CEO, CE = 110, OE = 96. By Pythagoras's theorem

OC^2 = OE^2 + EC^2 = 110^2 + 96^2 = 21316. This implies OC = 146

the correct ans is 146.....and say Thanks.....
