- DA is false but R is trueCorrect
Explanation
Radio waves do not bend in a magnetic field.
Assertion A is false because radio waves consist of photons, which carry no electrical charge. Magnetic fields only exert force on moving charged particles. Since radio waves are neutral, they pass through magnetic fields without being deflected.
Reason R is true because radio waves are indeed a type of electromagnetic radiation, occupying the long wavelength part of the electromagnetic spectrum.
Therefore, since the assertion is false and the reason is true, the correct option according to standard physics is D. If the question strictly follows the provided key A, it would be scientifically inaccurate.
