Correct answer: B

Step-by-Step Solution

To find the maximum percentage change over any two consecutive years, we calculate the growth for each wood type (P, ST, L) year-over-year.

  1. Understand the Formula: The percentage change is calculated as: ((Value_CurrentYear - Value_PreviousYear) / Value_PreviousYear) * 100.

  2. Analyze the Data Points (Approximation):

    • Wood Type P (Circle Marker):

      • 1987: 5000, 1988: 6200 -> Change = ((6200-5000)/5000) * 100 = 24%

      • 1988: 6200, 1989: 7000 -> Change = ((7000-6200)/6200) * 100 = ~12.9%

    • Wood Type ST (Square Marker):

      • 1987: 10000, 1988: 11000 -> Change = ((11000-10000)/10000) * 100 = 10%

      • 1988: 11000, 1989: 12000 -> Change = ((12000-11000)/11000) * 100 = ~9.1%

    • Wood Type L (Triangle Marker):

      • 1987: 13500, 1988: 15000 -> Change = ((15000-13500)/13500) * 100 = ~11.1%

  3. Conclusion: Comparing the calculated percentage changes, the growth of Wood Type P between 1987 and 1988 (approximately 24%) is the highest observed change in the graph.
