Tips:

It is necessary to check the sound of the word after which we are using a/an for vowels.

1.  Use 'an' when the word sounds with 'o'.

2. Use 'a' when the word sounds with 'w'.

Explanation:

Here, the word 'one' sounds with 'w'. Therefore, we use 'a' in this case.

Another example:

an orange.

As, the word 'orange'  sounds with 'o' , we use 'an' in this case.
