Các số thực x, y thỏa mãn: \({x^2} - y - \left( {y - 4} \right)i = i\) là

A. \(\left( {x;y} \right) = \left( {\sqrt 3 ;3} \right);\,\,\left( {x;y} \right) = \left( { - \sqrt 3 ;3} \right)\)

B. \(\left( {x;y} \right) = \left( {\sqrt 3 ;3} \right);\,\,\left( {x;y} \right) = \left( { - \sqrt 3 ; - 3} \right)\)

C. \(\left( {x;y} \right) = \left( { - \sqrt 3 ; - 3} \right);\,\,\left( {x;y} \right) = \left( { - \sqrt 3 ; - 3} \right)\)

D. \(\left( {x;y} \right) = \left( {\sqrt 3 ;3} \right);\,\,\left( {x;y} \right) = \left( {\sqrt 3 ; - 3} \right)\)
