If an option calls 3214 km the east-west extent in India's size, what is the correction?

Correct answer: 3214 km is north-south extent

India’s size is described with measurements that have specific directions. The north–south extent runs from the country’s northern boundary toward its southern end, while the east–west extent runs between its eastern and western limits. A figure of about 3,214 km belongs to the north–south extent. The east–west measurement is shorter, about 2,933 km. Keeping the direction attached to each number prevents a common examination error.

Option A is correct because it identifies 3,214 km as India’s north–south extent. It is not the length of the land boundary, the total coastline, or a measure of India’s share of the world. The question asks for the correction to a wrongly labelled east–west figure, so the answer must replace the direction rather than replace the number. The important recall pair is approximately 3,214 km north–south and 2,933 km east–west.
