Select the sentence in which the article has been wrongly used.

Question

Accepted Answer

The question asks to select the sentence in which the article has been wrongly used. The correct answer is Option 2.

Here's a detailed explanation:

**Why Option 2 is correct (i.e., the article is wrongly used):**

*   **Option 2: He is a M.A.**
    *   The choice between the indefinite articles 'a' and 'an' depends on the sound of the word immediately following the article, not necessarily the letter it starts with.
    *   'A' is used before words that begin with a consonant sound.
    *   'An' is used before words that begin with a vowel sound.
    *   When we pronounce the abbreviation "M.A.", the first sound is an "em" sound, which starts with a vowel sound (like the 'e' in 'egg').
    *   Therefore, the correct article to use before "M.A." should be 'an', not 'a'. The sentence should be "He is **an** M.A."
    *   Since 'a' is used instead of 'an', the article is wrongly used in this sentence.

**Why the other options are incorrect (i.e., the articles are correctly used):**

*   **Option 1: Twelve inches make a foot.**
    *   The word "foot" begins with a consonant sound (/f/).
    *   The article 'a' is correctly used before "foot" because it starts with a consonant sound.

*   **Option 3: A pupil should obey his teacher.**
    *   The word "pupil" begins with a consonant sound (/p/).
    *   The article 'a' is correctly used before "pupil" because it starts with a consonant sound.

*   **Option 4: He is a European.**
    *   Although the word "European" starts with the vowel letter 'E', its pronunciation begins with a consonant sound, specifically the /j/ sound (like the 'y' in 'you').
    *   Since the initial sound is a consonant sound, the article 'a' is correctly used before "European". The sentence is grammatically correct.

In summary, Option 2 is the only sentence where the article 'a' is used incorrectly because the following word "M.A." begins with a vowel sound, requiring 'an'.
