Explanation:

Let's break down the correct dictionary order for the words:

- Relatable

- Related

- Relation

- Relatival

- Relative

Order explanation:

- First, we compare letter by letter.

- “Relat-” is common to all.

- Next letters: a (ble), e (d), i (on), i (val), i (ve)

- 'Relatable' comes before 'Related' (b before d).

- 'Related' comes before 'Relation' (d before i).

- 'Relatival' and 'Relative' both share 'Relativ', but 'al' comes before 'e'.

So correct order: Relatable, Related, Relation, Relatival, Relative

Let's look for the correct option:

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

This corresponds to:

4. Relative

5. Relatable

3. Related

2. Relation

1. Relatival

[But this order is not correct.]

- The correct order is: 5, 3, 2, 1, 4

Relatable (5), Related (3), Relation (2), Relatival (1), Relative (4)

To summarize:

- Start comparing after the common root.

- Follow alphabetical order letter-by-letter.

- Correct order is 5, 3, 2, 1, 4.

- Among given options, none exactly match, but your option does not list the correct order.
