Between which colours is blue-green found on the colour wheel?

Correct answer: Green and blue

The governing concept is that a tertiary colour occupies the interval between its two neighbouring colours on the colour wheel. Blue-green is positioned between blue and green, which is the same pair written in reverse order in option B. Yellow-green lies between yellow and green, blue-violet between blue and violet, and red-orange between red and orange, so the remaining options are incorrect.
