What is the average cost of a six-foot Christmas tree in Prague, as mentioned in a survey?

The correct answer reflects the average cost of a six-foot Christmas tree in Prague according to the survey. A price of €11 indicates a reasonable and realistic average for the cost of a decorative item like a Christmas tree, considering factors such as the price of living in Prague, market conditions, and typical pricing for seasonal goods.

In comparison to the other options, €5 might be too low when considering the expense of Christmas trees, which often include costs for cultivation, transportation, and sale. Meanwhile, prices like €146 and €200 suggest a much higher-end market that would not align with the average expenditure for such a common holiday item, making €11 a fitting price point for the average consumer looking to purchase a Christmas tree in the city.
