Correct Answer: C — 1 and 2 only
Explanation:
Stealth platforms aim to reduce radar cross-section and often use radar-absorbing materials, so statement 1 is accepted. They can still be detected under some conditions or frequency bands, so statement 2 is accepted. Statement 3 is rejected because stealth design aims to reduce or control reflection and scattering, not increase electromagnetic scattering.
