A0, 1, 2, 3, 4 — the sequence starts at zero and excludes the stop value
B1, 2, 3, 4, 5 — the sequence starts at one and includes the stop value
C0, 1, 2, 3, 4, 5 — the sequence covers every number up to and including 5
D5, 4, 3, 2, 1 — the sequence counts down from the argument toward one
Why this is the answer
range(stop) yields 0 up to stop-1. It doesn't start at 1, never includes the stop value, and counts upward — descending ranges need an explicit negative step like range(5, 0, -1).
