Step 1: Understanding the Sunrise Colour Effect.
During sunrise, the sky often appears to be painted with warm hues like orange, red, and yellow. The orange colour is particularly common as the sun rises and scatters light in the atmosphere.
Step 2: Verifying the Options.
- Option (1): Violet is more common at sunset, not sunrise.
- Option (2): Yellow appears in the sky, but orange is more prominent at sunrise.
- Option (3): Orange is the correct colour that commonly appears during sunrise.
- Option (4): Red can appear during sunrise but is less common than orange.
Conclusion:
Therefore, the correct answer is (3) Orange.
