In general, which of the following does not comes under the category of Primary colors?

In the traditional color models, primary colors are the basic colors that cannot be created by mixing other colors. In the RYB (Red, Yellow, Blue) model used in art, and RGB (Red, Green, Blue) model used in light, Cyan is not a primary color - it's a secondary color formed by mixing blue and green (in light) or blue and yellow (in pigment). Therefore, Cyan does not come under primary colors in general color theory.
