Which of the following statements with regard to stealth technology is/are correct?

Stealth objects have a very small radar cross-section and are coated with Radar Absorbing Material.
Stealth objects can be detected using specific frequencies.
Stealth objects are coated with metamaterials to increase the scattering of electromagnetic radiation.

Select the answer using the code given below:

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.
