____ ने PWD (Public Works Department) नावाचे स्वतंत्र एक खातेच निर्माण करून हिंदुस्थानात रस्त्यांचे जाळेच निर्माण केले.

The correct answer is Option B (लॉर्ड डलहौसी).

Key Points:
• The key concept is infrastructural developments during the British colonial period.
• Before Lord Dalhousie, public works were the responsibility of the Military Board. This was highly inefficient.
• Lord Dalhousie, during his tenure as Governor-General (1848–1856), created a separate civilian Public Works Department (PWD). Under this department, extensive road networks (including the repair of the Grand Trunk Road), canals (like the Ganges Canal), and bridges were constructed across India.
• Lord William Bentinck is known for social reforms (abolition of Sati).
• Key Takeaway: Lord Dalhousie established a separate Public Works Department (PWD) in India for infrastructure development.
