Who among the following advocated the construction of initial railways in India for facilitating army movement?

Lord Dalhousie, the Governor-General of India (1848–1856), is widely regarded as the "Father of Indian Railways." In his famous Railway Minute of 1853, he proposed a comprehensive plan for a railway network in India. He argued that railways would provide significant military advantages by allowing for the rapid movement of troops and equipment to any part of the country, thereby enhancing internal security and frontier defense with a smaller standing army. Additionally, he highlighted the commercial benefits, such as the efficient transport of raw materials like cotton from the hinterlands to the ports for export to Britain. The first railway line in India, between Bombay and Thane, was opened during his tenure in 1853.
