Select the option that indicates the correct arrangement of the given words in the order in which they appear in an English dictionary.
1. Kibble
2. Kennel
3. Kettle
4. Kicker
5. Kernel

To arrange the words in alphabetical order as they appear in an English dictionary, we compare them letter by letter from left to right:
All words start with 'K'. Let's look at the second letter:

* Kennel ('e')
* Kettle ('e')
* Kernel ('e')
* Kibble ('i')
* Kicker ('i')

Since 'e' comes before 'i', we first arrange the words starting with 'Ke':

1. Compare Kennel, Kettle, Kernel:
* Third letters are 'n', 't', 'r'.
* In alphabetical order: 'n' comes first, then 'r', then 't'.
* Therefore, the order is: Kennel (2) $\to$ Kernel (5) $\to$ Kettle (3).

Next, we arrange the words starting with 'Ki':
2. Compare Kibble, Kicker:

* Third letters are 'b' and 'c'.
* Alphabetically, 'b' comes before 'c'.
* Therefore, the order is: Kibble (1) $\to$ Kicker (4).

Combining both sequences gives the final dictionary order:
2, 5, 3, 1, 4

This matches Option D.
