Choose the correct preposition to fill in the blank: The Rajdhani Exp…

The correct answer is Option (4) → at

Note: The given answer is as per the official NTA Answer Key. However, more than one answer is possible here: Option (4) "at" and Option (2) "on" both make a correct sentence, as explained below.

Option 1: in — Incorrect.

• After arrive, "in" is used for a city or a country (arrive in Delhi, arrive in India).
• A platform is a particular point at a station, not a city or a country, so "arrive in platform No. 3" is wrong.
  Example: The team will arrive in Mumbai tomorrow.

Option 2: on — Can also be considered as correct.

• On is used for a surface or a platform where something stands or stops.
• "The train will arrive on platform No. 3" is the usual wording of railway announcements in India and in Britain, so "on" also makes a correct sentence.
  Example: The Shatabdi Express will arrive on platform No. 1.

Option 3: into — Incorrect.

• Into shows movement from outside to inside.
• A train does not arrive "into" a platform; "arrive into platform No. 3" is not standard usage.
  Example: She walked into the room.

Option 4: at — Correct (Answer as per NTA).

• At is used for a particular point or place, such as a station, a bus stop or a platform; we arrive at a point or a building and in a city or a country.
• Platform No. 3 is the fixed point where the train stops, so "at" is correct.
• Complete sentence: The Rajdhani Express is due to arrive at platform No. 3.
  Example: Our flight will arrive at Terminal 2.
