Step 1: Understanding Secondary Colours.
Secondary colours are created by mixing two primary colours. There are three
secondary colours in traditional colour theory:
- Orange (created by mixing red and yellow)
- Green (created by mixing yellow and blue)
- Violet (created by mixing blue and red)
Step 2: Verifying the Options.

- Option (2): There are 3 secondary colours: orange, green, and violet.
- Option (3): Two secondary colours are incorrect.

Conclusion:
Therefore, the correct answer is (2) 3.
