Which secondary colours are placed near blue on a traditional colour wheel?

Correct answer: Green and Violet

The governing concept is the traditional RYB colour wheel. Blue is a primary colour positioned between green and violet. Yellow mixed with blue produces green, while red mixed with blue produces violet. Thus green and violet lie on the two sides of blue, so option B is correct. Orange is made by mixing red and yellow and is positioned away from blue; yellow and red themselves are primary colours.
