Match List I with List II and select the correct answer using the codes given below the List.

(Cities Connected) | (National Highway)
A. Agra-Mumbai | 1. NH 21
B. Varanasi- Kanyakumari | 2. NH 7
C. Chandigarh- Manali | 3. NH 3
D. Delhi-Jaipur | 4. NH 8

The correct answer is Option 1 (A-3, B-2, C-1, D-4) based on the traditional National Highway numbering system in India.

• A-3: NH 3, famously known as the Agra-Bombay Highway, is a vital north-south corridor connecting Uttar Pradesh to Maharashtra.
• B-2: NH 7 was historically the longest highway in India, stretching from Varanasi in the north to Kanyakumari at the southern tip.
• C-1: NH 21 is a significant highway in the Himalayan region, connecting Chandigarh to the tourist hub of Manali.
• D-4: NH 8 is one of the busiest highways, part of the Golden Quadrilateral, linking Delhi to Mumbai via Jaipur.

Other options are incorrect because they mismatch these established routes. For instance, Option 4 suggests NH 21 connects Agra-Mumbai, which is geographically inaccurate as NH 21 serves the northern hilly terrain.
