If \( z_{1}, z_{2}, z_{3} \) are three complex numbers and \( A=\left|\begin{array}{ccc}\arg z_{1} & \arg z_{2} & \arg z_{3} \\ \arg z_{2} & \arg z_{3} & \arg z_{1} \\ \arg z_{3} & \arg z_{1} & \arg z_{2}\end{array}\right| \) then \( A \) is divisible by
(a) \( \arg \left(z_{1}+z_{2}+z_{3}\right) \)
(b) \( \arg \left(z_{1} z_{2} z_{3}\right) \)
(c) all numbers
