Which option represents the correct order of the given words as they would appear in an English dictionary?
Illustrate

Illustration

Illustrator

Illuminate

Illumination

Let's arrange the words alphabetically by comparing letter by letter:
All words start with "Illu". Let's look at the 5th letter:

Illustrate (s)

Illustration (s)

Illustrator (s)

Illuminate (m)

Illumination (m)

Comparing 'm' and 's', 'm' comes first. So words 4 and 5 come before 1, 2, and 3.

Between 4 (Illuminate) and 5 (Illumination):

Both have "Illuminat"

4 has 'e' as the 10th letter.

5 has 'i' as the 10th letter.

Since 'e' comes before 'i', the order is 4, 5.

Now, between 1, 2, and 3:

Illustrate

Illustration

Illustrator

All share "Illustrat"

1 ends here (or has no further letters), so it comes first → 1

2 has 'i' after "Illustrat" → 2

3 has 'o' after "Illustrat" → 3

Combining them, the correct alphabetical dictionary order is: 4, 5, 1, 2, 3.
