Which GB point lies posterior to the ear along a curved line from GB-9 to GB-12 at distance greater than two thirds?

Explanation:
The key idea here is the relative positions along the Gall Bladder line behind the ear. On the curved path from GB9 toward GB12, the points are arranged sequentially from near the temple to behind the ear toward the mastoid region. The point that sits behind the ear at roughly two-thirds of that distance is GB11. It lies in a shallow depression behind the ear near the mastoid area, making it the spot described. GB10 is closer to GB9, GB12 is farther back toward the base of the skull, and GB13 lies on a different line higher up, not on this posterior path. So GB11 is the correct choice.
