aOnly one
bOnly two
cAll three
dNone
✓ Correct answer: d) None
ExplanationFifth-generation fighter aircraft typically have features like stealth, advanced avionics, sensor fusion, and supercruise capability.Examples include the F-35 Lightning II (USA), F-22 Raptor (USA), Su-57 (Russia), and J-20 (China).They differ from fourth-generation aircraft primarily in their stealth features.Fifth-generation aircraft have a low electro- magnetic signature, which makes it difficult for enemy radar to detect them.At the same time, fifth-generation aircraft have powerful sensors and new weapons, so they are able to register the signature of enemy aircraft and take them out.Option 1 is incorrect: Rafale is a 4.5-generation multirole fighter developed by Dassault Aviation (France).It features advanced avionics, stealth enhancements, and superior maneuverability but lacks full stealth and sensor fusion, which are key traits of fifth-generation aircraft.Option 2 is incorrect: MiG-29 is a fourth-generation fighter developed by Russia, primarily designed for air superiority with high agility but lacks stealth technology.Option 3 is incorrect: Tejas MK-1 is an indigen
