Choose the sentence in which the article is used incorrectly:

The correct answer is Option (4) → Our neighbours have gone to Philippines for a week.

“The” before a plural country name:

The given sentence says “gone to Philippines”. This is wrong. Most country names take no article. But a country whose name is in the plural takes “the”. “Philippines” ends in -s because the country is made up of many islands.

Corrected: Our neighbours have gone to the Philippines for a week.

Why the Other Options are Incorrect?

Option 1: My aunt travels to Pune by train every Friday. This sentence is correct. After “by” with a way of travel (by bus, by train), no article is used.

Option 2: Every student must wear a uniform on Mondays. This sentence is correct. “Uniform” begins with a “yoo” sound, which is a consonant sound, so it takes “a”.

Option 3: This is the oldest banyan tree in our village. This sentence is correct. “The” comes before the highest form of a describing word, such as “oldest”.
