Which one of the following is the country's administrative capital/new federal administrative centre of Malaysia ?

Putrajaya is Malaysia’s purpose-built federal administrative centre. The planned city was developed in the 1990s to relocate the federal government away from overcrowded Kuala Lumpur; in 1999 Putrajaya became the new seat of the Malaysian federal government and now hosts many government offices and judicial functions, while Kuala Lumpur remains the national/legislative and commercial capital [2]. Located roughly 25 km south of Kuala Lumpur, Putrajaya was conceived as a more orderly, greener and efficient administrative hub as part of a deliberate decentralization and urban-design strategy. Hence the correct answer is Putrajaya (option 3).
