Choose the sentence in which the article is used incorrectly:

The correct answer is Option (1) → Papa gave me an advice about which subjects to choose after Class 10.

No “a” or “an” before “advice”:

The given sentence says “an advice”. This is wrong. “Advice” is a noun that cannot be counted. We cannot say one advice or two advices. So it never takes “a” or “an”. We say “some advice” or “a piece of advice”.

Corrected: Papa gave me some advice about which subjects to choose after Class 10.

Why the Other Options are Incorrect?

Option 2: Kerala is famous for its backwaters and coconut trees. This sentence is correct. The name of a state, like most city and country names, takes no article.

Option 3: We went snorkelling in the Lakshadweep Islands last winter. This sentence is correct. “The” comes before the name of a group of islands.

Option 4: It was such a crowded train that we stood all the way to Pune. This sentence is correct. “Such” before a singular noun that can be counted is followed by “a” or “an”. “Crowded” begins with a consonant sound, so it takes “a”.
