Show answer and explanation

Correct answer: (C) The largest reduction for a 5000-step increment is from 0 to 5000.

Explanation

The curve falls most steeply initially and then flattens. Risk drops from about 1 to 0.43 over the first 5000 steps, compared with progressively smaller drops in later equal intervals. Thus the greatest plotted reduction is **0–5000, C**.
