Statement 1 is incorrect as the Mirage 2000 is a single-engine fighter jet, not a twin-engine.

Statement 2 is correct. The HAL Tejas is, indeed, a delta-winged fighter jet, meaning it`s a jet with triangular wings, similar in shape to the Greek letter delta.

Statement 3 is incorrect. The Rafale is a twin-engine fighter jet, not a hypersonic jet. Hypersonic jets are a type of aircraft that can travel at speeds greater than Mach 5, and as of now, there is no military fighter jet globally that can achieve this speed.

The options represent combinations of these statements, with the correct answer being option 2, indicating that statement 2 is the only correct statement.

All other options include at least one incorrect statement making them false.
