Choose the option which is incorrect :

The correct answer is Option (4) → How far destination it is!

Patterns of exclamatory sentences:

• What + a/an + adjective + noun! — "What" is followed by a noun phrase.
• How + adjective/adverb + subject + verb! — "How" is followed by an adjective or adverb, not by a noun phrase.
• This sentence: "How far destination it is!" puts a noun ("destination") after "How far" and drops the article.
  Corrected: How far the destination is! (or What a distant destination it is!)
  Example: How far the station is!

Why the Other Options are Incorrect?

Option 1: What a lovely day! — Incorrect. Correct use: What + a + adjective (lovely) + noun (day).

Option 2: What a pretty dress! — Incorrect. Correct use: What + a + adjective (pretty) + noun (dress).

Option 3: What an intelligent child! — Incorrect. Correct use: "an" is rightly used before the vowel sound of "intelligent".
