According to lane size and quality, arrange the types of roads in an ascending order.
A. Highway
B. Metalled Rural Roads
C. Expressways
D. Unmetalled Roads
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → D, B, A, C
D. Unmetalled Roads — first, the lowest. They are simple in construction and cannot be used in all seasons; in the rains they become unmotorable.
B. Metalled Rural Roads — second. Being metalled, they are better than unmetalled roads, but they lack the width, separate traffic lanes and flyovers of a highway.
A. Highway — third. Highways are metalled roads about 80 m wide, with separate traffic lanes, bridges, flyovers and dual carriageways.
C. Expressways — last, the highest. The Golden Quadrilateral, a super expressway, is a 4/6 lane, high density traffic corridor.
Note: The given answer is as per the official NTA Answer Key. The book does not rank these four kinds of roads in one list. The order follows from the book’s description of each: unmetalled roads are not serviceable in all seasons, highways are wide metalled roads with separate traffic lanes, and the Golden Quadrilateral super expressway is a 4/6 lane corridor.
NCERT (2026-27): “Roads … Road transport is the most economical for short distances compared to railways. Freight transport by road is gaining importance because it offers door-to-door service. But unmetalled roads, though simple in construction, are not effective and serviceable for all seasons. During the rainy season these become unmotorable and even the metalled ones are seriously handicapped during heavy rains and floods.” “Highways … Highways are metalled roads connecting distant places. They are constructed in a manner for unobstructed vehicular movement. As such these are 80 m wide, with separate traffic lanes, bridges, flyovers and dual carriageways to facilitate uninterrupted traffic flow.” “In India, there are many highways linking the major towns and cities. The Golden Quadrilateral (GQ) or Super Expressway connect the four metropolitan cities — New Delhi, Mumbai, Chennai and Kolkata.”
