Solution:
Area of the circle=π\(r^2\).
64π=π\(r^2\)
r=8
Thus, if AB/AC is on the diameter it can be 16.
But both of them cannot be on the diameter and one of them has to be less than 16.
Making the sum of the two less than 32
Qty A< Qty B
IMO B
Hope this helps!

i understand your reasoning but, the info only said 3 point of circle and nothing else
from that we can consider there may two diameter or two chords or one diameter and one chord....shouldn't ans be option D not sufficient into to reach one result
