Government of India has formulated a Greenfield Airports (GFA) Policy, 2008 for development of new Greenfield airports in the country. As per the policy, if any developer including the State Government desires to develop an airport, they are required to identify a suitable site and get the Pre-feasibility Study conducted for construction of airport and submit a proposal to the Central Government for 'Site Clearance' followed by 'In- Principle' approval. Government of India has accorded 'In-Principle' approval for setting up of 21 new Greenfield Airports namely, Mopa in Goa, Navi Mumbai, Shirdi and Sindhudurg in Maharashtra, Kalaburagi, Vijayapura, Hassan and Shivamogga in Karnataka, Dabra (Gwalior) in Madhya Pradesh, Kushinagar and Noida (Jewar) in Uttar Pradesh, Dholera and Hirasar in Gujarat, Karaikal in Puducherry, Dagadarthi, Bhogapuram and Orvakal (Kurnool) in Andhra Pradesh, Durgapur in West Bengal, Pakyong in Sikkim, Kannur in Kerala and Hollongi also known as Donyi Polo (Itanagar) in Arunachal Pradesh across the country. Vijayawada Internatioanal Airport is not a Greenfield airport. Hence option (a) is the correct answer.
