an i think it is correct

Answer 2

Answer :

This question is based on articles.

The correct sentence is :

He came an hour late.

Merriam-Webster Dictionary defines 'article' as 'any of a small set of words or affixes (such as a, an, and the) used with nouns to limit or give definiteness to the application.'

In the given sentence, the indefinite article 'an' is used as an unspecific object is being referred to. Moreover, the letter 'h' in the word 'hour' is silent, so it begins with a vowel sound.
