Select the option that represents the correct order of the given words as they would appear in an English dictionary.
1. Ferocious
2. Fervor
3. Fiction
4. Faith
5. Feign
6. Ferment

Let's arrange the given words in alphabetical order step by step by comparing their letters:
7. Compare by the 2nd letter:
* 4. Faith has 'a' as the second letter. This comes first. $\to$ (4)
* 5. Feign has 'e' as the second letter. Since 'e' comes after 'a' but before 'i' and 'o', we look at words starting with 'Fe' and 'Fe' comes before 'Fi'.
Let's check the group of words starting with 'Fe': 1. Ferocious, 2. Fervor, 5. Feign, 6. Ferment.
* Comparing their 3nd letters: 5. Feign ('i') comes before 'r' in the other three words. So, 5 comes second. $\to$ (4, 5)

8. Now sort the remaining words starting with 'Fer' (1. Ferocious, 2. Fervor, 6. Ferment) by their 4th letter:
* 6. Ferment ('m')

* 1. Ferocious ('o')

* 2. Fervor ('v')
Comparing 'm', 'o', and 'v': 'm' comes first, then 'o', then 'v'.

* Therefore, the order of these three is 6, then 1, then 2. $\to$ (4, 5, 6, 1, 2)

9. Finally, look at the last remaining word:
* 3. Fiction has 'i' as the second letter, so it naturally comes last after all words starting with 'Fa' and 'Fe'. $\to$ (4, 5, 6, 1, 2, 3)

The correct alphabetical dictionary order is: 4, 5, 6, 1, 2, 3.
