This question is about understanding market dynamics. The correct answer is 'B. High demand for real estate' because steady home prices often indicate a balanced market with consistent demand. 'A. Increase in interest rates' generally leads to a decrease in demand and potential decline in prices. 'C. Decrease in consumer confidence' would likely lead to a decrease in demand and prices. 'D. Government intervention in the housing market' could affect prices, but there is no mention of such intervention in the text.
