Answer 2

Answer:

He is an SDO.

The article will be "an".

Explanation:

• Article - An article is a word that defines a noun specific or unspecific.

There are two types of articles -

1. Definite Article - "The" is the definite article. It limits the meaning of a noun to one particular thing. The definite article can be used with singular, plural or uncountable nouns to specify them. For example - The Himalaya, The Ramayana etc.
2. Indefinite Article - "A" and "An" are the two indefinite articles.

• "A" is used before a noun having a consonant sound. For example - A boy, A river, A man etc.
• "An" is used before a noun having a vowel sound. For example - An ox, An umbrella, An ant etc.

Here the noun is "SDO". "S" is a consonant but the word "SDO" begins with a vowel sound "A".

Thus there will be "an" before "SDO".
