A) Quantity A is greater.
B) Quantity B is greater.
C) The two quantities are equal.
D) The relationship cannot be determined from the information given.
Since AD is the diameter, \(\angle{ACE} + \angle{CDE} => x + 90° + 2x = 180° => x = 30°\)
So \( \angle{ACB} = 180° - 3x -10° = 180° - 90° -10° = 80°\)
Quantity B is larger, Answer is B)
