Explanation:

- Statement 1: Scramjet engines are designed to operate efficiently at supersonic speeds, not both subsonic and supersonic modes. They are specifically for speeds greater than Mach 5.

- Statement 2: India is not the first country to demonstrate a scramjet engine; other countries, such as the USA, have conducted successful tests earlier.

- Option 1: 1 only - Incorrect as scramjets are specifically for supersonic speeds.

- Option 2: 2 only - Incorrect since India was not the first to test scramjets.

- Option 3: Both 1 and 2 - Both statements are incorrect.

- Option 4: Neither 1 nor 2 - Correct, both statements are not accurate.
