Select the option that represents the correct order of the given words as they would appear in an English dictionary.

1. Infant

2. Indolent

3. Inert

4. Infamous

5. Inefficient

6. Ineffable

The correct order of the given words as they would appear in an English dictionary is 2, 6, 5, 3, 4, 1.

To find the dictionary order, we compare the given words alphabetically letter by letter from left to right:

1. All words start with the prefix In-.
Comparing the 3rd letters ('d', 'e', and 'f'):
- Indolent (2) has 'd' as its 3rd letter. Since 'd' comes before 'e' and 'f' in the alphabet, Indolent (2) comes first.

2. Next, compare words with 'e' as the 3rd letter (Ineffable, Inefficient, and Inert):
- Ineffable (6): I-N-E-F-F-A...
- Inefficient (5): I-N-E-F-F-I...
- Inert (3): I-N-E-R...
Comparing the 6th letters: 'a' in Ineffable comes before 'i' in Inefficient, and 'f' comes before 'r' in Inert. Thus, the relative order is 6 → 5 → 3.

3. Finally, compare words with 'f' as the 3rd letter (Infamous and Infant):
- Infamous (4): I-N-F-A-M-O-U-S
- Infant (1): I-N-F-A-N-T
Comparing the 5th letters: 'm' comes before 'n', so Infamous (4) comes before Infant (1). The relative order is 4 → 1.

Combining all the steps, the correct dictionary order is:
2, 6, 5, 3, 4, 1
