Why the answer is C, and why the others tempt you.
Prevalence rate is calculated as (number of cases ÷ total population) × 100. Here, (250 ÷ 5,000) × 100 = 5%. Option A (2%) would correspond to 100 cases, option B (4%) to 200 cases, and option D (10%) to 500 cases, making them incorrect distractors.
