Which of the following is NOT a characteristic of National Highways in India?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Construction of border roads in high-altitude areas.
The construction of border roads in high-altitude areas is a characteristic specific to the Border Roads Organisation (BRO) and is primarily driven by defence and strategic needs.
On the other hand, National Highways are built to facilitate civilian transportation and economic activities across India.
Therefore, constructing border roads in high-altitude areas is not a characteristic of National Highways in India.
