The metro rail system was constructed by L&T Metro Rail Hyderabad Limited (L&TMRHL), a joint venture between Larsen & Toubro and the Government of Telangana. The metro rail system was inaugurated on 28 November 2017.

The Hyderabad Metro Rail is an example of Telangana’s investment in urban infrastructure. The metro rail system is expected to improve the transportation system in Hyderabad and reduce traffic congestion. The metro rail system is also expected to boost economic growth in Hyderabad.

The other options are incorrect because they are not examples of Telangana’s investment in urban infrastructure. Agriculture is the practice of cultivating plants and livestock. Manufacturing is the process of making goods from raw materials. Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits.
