The following graph shows the average profit of two fruit-sellers A and B in thousands (₹) per year from the year 1995 to 2000. Consider the graph and answer the 4 (four) items that follow. What is the trend of the average profit of B from the year 1997 to the year 2000?

1. **Isolate the Data**: Look at the graph and find Line B (the thin line with dots). Focus your eyes only on the section from the year 1997 to 2000.\n\n2. **Observe the Movement**: \n - At 1997, the value is 4.\n - At 1998, the value is still 4. The line is flat (horizontal).\n - At 1999, the line goes up to 5.\n - At 2000, the line goes up further.\n\n3. **Analyze the Trend**: The graph shows a period of no change followed by a period of increase. Crucially, the line **never goes down**.\n\n4. **Test the Options**:\n - (A) *Non-increasing*: This means it stays flat or goes down. Since our line goes up, this is wrong.\n - (C) *Steady*: This means it never changes. Since our line goes up after 1998, this is wrong.\n - (D) *Fluctuating*: This implies ups and downs. Our line never goes down, so it is not fluctuating.\n - (B) *Non-decreasing*: This allows for the value to stay the same or go up. It fits perfectly: it stays the same (1997-98) and then goes up (1998-2000).
