Choose the sentence in which the article is used incorrectly:

The correct answer is Option (3) → The porter carried a heavy luggage to our coach.

No “a” before a noun that cannot be counted:

The given sentence says “a heavy luggage”. This is wrong. “Luggage” is a noun that cannot be counted, like “furniture” or “advice”. Such a noun never takes “a” or “an”. We can say “heavy luggage” or “a heavy bag”.

Corrected: The porter carried heavy luggage to our coach.

Why the Other Options are Incorrect?

Option 1: Kolkata was once the capital of India. This sentence is correct. A country has only one capital, so “the capital” is right.

Option 2: My cousin works as an actor in Marathi films. This sentence is correct. A job takes “a” or “an”, and “actor” begins with a vowel sound, so it takes “an”.

Option 4: Priyanka is learning French at a language school. This sentence is correct. The name of a language, such as French, takes no article.
