Explanation:

Let’s check the correct dictionary order:

- Interaction (3): Starts with "Interac—"

- Interjection (4): "Interj—" comes after "Interac—"

- Internship (2): "Intern—" comes after "Interj—"

- Interruption (6): "Interr—" comes after "Intern—"

- Intervene (5): "Interv—" comes after "Interr—"

- Introduce (1): "Intro—" comes after "Interv—"

Now check each option:

- Option 1: 1, 3, 2, 4, 6, 5 (No, starts with Introduce which is last)

- Option 2: 2, 3, 4, 2, 6, 5, 1 (Repeats 2, too many options)

- Option 3: 3, 4, 2, 6, 1, 5 (Correct logical order except 1 & 5 swapped)

- Option 4: 4, 2, 5, 6, 1 (Wrong order entirely)

Correct answer:

- 3, 4, 2, 6, 5, 1

- Interaction

- Interjection

- Internship

- Interruption

- Intervene

- Introduce

Option 3 is correct.

Explanation:

- Look for the common prefix, compare next unique letter.

- “Interac—, Interj—, Intern—, Interr—, Interv—, Intro—” is the alphabetical sequence.

- Option 3 alone matches this sequence.

Each provided option should list all six items, one time each, in order; only Option 3 does that logically.
