In the context of India's defence, consider the following pairs: Aircraft Type : Description I. Dornier-228 : Maritime patrol aircraft II. IL-76 : Supersonic combat aircraft III. C-17 Globemaster III : Military transport aircraft How many of the above pairs are correctly matched?

Pair I is correct: Dornier-228 is a twin-engine turboprop aircraft used by the Indian Navy and Coast Guard for maritime patrol, surveillance, and reconnaissance. Pair II is incorrect: IL-76 (Ilyushin Il-76) is a heavy strategic airlift transport aircraft, not a supersonic combat aircraft. Pair III is correct: C-17 Globemaster III, manufactured by Boeing, is a large military transport aircraft used by the Indian Air Force for strategic airlift of troops and cargo. Hence only two pairs are correctly matched.
