Answer 2

Answer:

Option 2 - a number

Explanation:

• There are three articles in English: a, an, and the. Articles are a sort of adjective that are used before nouns or noun equivalents. The definite article (the) is used before a noun to emphasise that the reader is aware of the word's identity.
• Articles are prefixes that appear before nouns or noun phrases. They, like other adjectives, aid in the clarification of the meaning of the noun in your phrase. There are just two articles in English: the and a. (and its variant an, used before a word that starts with a vowel sound).
• An article is a word that comes before a noun to indicate whether the reference is to a specific entity or entities or to something in general. A, an, and the are the only articles. The indefinite articles a and an are used to refer to a single, indeterminate entity.
