Giải phương trình (sin left( {frac{{2x}}{3} - frac{pi }{3}} ight) = 0).

A. \(x = k\pi {\rm{ }}\left( {k \in Z} \right).\)

B. \(x = \frac{{2\pi }}{3} + \frac{{k3\pi }}{2}{\rm{ }}\left( {k \in Z} \right).\)

C. \(x = \frac{\pi }{3} + k\pi {\rm{ }}\left( {k \in Z} \right).\)

D. \(x = \frac{\pi }{2} + \frac{{k3\pi }}{2}{\rm{ }}\left( {k \in Z} \right).\)
