I went on using distance formula finding the distance OC and CB which I got 5/3 and 4/3 respectively. Then comparing these two I answered B. But I used too much time on this as it was only 1 mark.
i also did the same...i wrote that it was nearer to B..hope its correct!!:confused:

I hope the GT lies somewhere between 60-70.. *fingers crossed* ^_^
60- 70 is somethin to big for a margin..... a will be least scored for not above 63-64 mark my words... and that is also when the paper was done too well by all.
