Which of the following pairs is not correctly matched?

Option 2 is incorrect. The Arjun is an indigenously designed and produced main battle tank of India [1]. The Phalcon is not a cruise missile supplied by Russia; it is an airborne early warning and control (AWACS) system procured from Israel (fitted to an Ilyushin‑76 platform under a tripartite India‑Israel‑Russia deal) and is used for long‑range surveillance and detection, including cruise‑missile detection, not as a missile itself. Saras refers to the indigenous civilian passenger aircraft project developed by NAL/India (correct), and the new Indian naval base at Karwar is part of Project Seabird (correct) [2].
