राष्ट्रीय महामार्ग विकास प्रकल्प (NHDP) उच्च गुणवत्तेचे महामार्ग बांधण्याशी संबंधित आहे, आणि प्रधानमंत्री भारत जोडो परियोजना (PMBJP)_______ संबंधित आहे.

The correct answer is Option C (linking up major cities to highways).

Key Points:
• The correct option is (3).
• Road Infrastructure Initiatives:
• National Highways Development Project (NHDP): Initiated in 1998 under Prime Minister Atal Bihari Vajpayee, focusing on the Golden Quadrilateral (linking Delhi, Mumbai, Chennai, Kolkata) and the North-South & East-West Corridors.
• Pradhan Mantri Bharat Jodo Pariyojana (PMBJP): Initiated in 2003-04 by the NDA government to complement NHDP by linking up major cities, state capitals, and economically significant growth centres to the newly developed National Highway network via four-lane connectivity.
• Clarification:
• Building rural roads and connecting rural areas to urban centres is the specific mandate of the Pradhan Mantri Gram Sadak Yojana (PMGSY, launched December 2000).
• Key Takeaway: While NHDP developed arterial national highway corridors, PMBJP linked major urban cities to these highway grids.
