For which of the following inequalities is the solution set represented by the interval [-3, 5]?

A |x - 1| ≤ 4
B |x + 1| ≤ 4
C |x - 2| ≤ 3
D |x + 2| ≤ 3

✓ Correct Answer: Option A

The midpoint of the interval [-3, 5] is ((-3) + 5) / 2 = 1. The distance from the midpoint to either endpoint is 5 - 1 = 4. Therefore, the inequality is of the form |x - midpoint| ≤ distance, which is |x - 1| ≤ 4.
