Explanation:

Let’s break this down word by word, and see how they’d line up in a real English dictionary:

- Righteous comes first—after “righteous,”

- Rightly follows—"rightl-" comes after "righte-",

- Rights is after “rightly”—the “s” tips it just past “rightly,”

- Rigidly is next—now we leave the “right-” entries and move into “rigid-,”

- Rigour is last, being “rigo-,” which comes after “rigi-“ since “o” is after “i.”

Now, let’s see your options:

1. Option 1: 1, 3, 5, 1, 4, 2

(Rightly, Righteous, Rights, Rightly, Rigour, Rigidly) — Repeats and messed order.

2. Option 2: 2, 3, 1, 5, 4, 2

(Rigidly, Righteous, Rightly, Rights, Rigour, Rigidly) — Out of order, Rigidly way too early.

3. Option 3: 3, 1, 5, 2, 4

(Righteous, Rightly, Rights, Rigidly, Rigour) —

This is correct.

4. Option 4: 1, 3, 5, 2, 4

(Rightly, Righteous, Rights, Rigidly, Rigour) — Has Righteous after Rightly; not right.
