OA is A but i guess it should be E
i understand the entire question. we simply find the diagonal which is equal to 10. as diagonal = radius thus radius is 10. now the two points are (8,6) it means length of OJ is 6 not 8. thus JK = 10-6 = 4

Hi sana.noor,

Yes, the length of JK = 4. It's possible that the person who wrote this question was looking at ML (instead of JK). The length of ML = 2. Thankfully, the GMAT doesn't make these mistakes.

You're right. The answer is E indeed.
