What do the colours of the Union Jack represent?

The correct answer highlights that the colours of the Union Jack represent the flags of England, Scotland, and Ireland. The Union Jack is a composite flag that combines elements from these three countries. The red cross of St George represents England, while the white saltire of St Andrew represents Scotland. The union of these two elements is combined with the red saltire of St Patrick, representing Ireland. This amalgamation symbolizes the political union of these countries within the United Kingdom.

Wales is not represented in the Union Jack, as at the time of its creation, the Welsh dragon was not included in the design. Thus, choices that cite either Wales or create different combinations of country representations are incorrect, as they do not accurately reflect the historical origins of the flag's components. Understanding the significance of each element and their contributions to the Union Jack is essential for grasping British history and nationality, particularly in the context of the citizenship test.
