Detailed Solution

Concept- Understanding the fundamental characteristics of electromagnetic waves, such as the fact that they are created by magnetic and electric fields, would help in answering this theory-based question.
Electric and magnetic fields create EM waves, but they do not deflect them. Gravitational fields can also deflect EM waves. Since light is an electromagnetic wave with both an electric and a magnetic field, it should cause a compass needle to be redirected during the day. Glass reflects visible light because it is an electromagnetic wave (take mirror). Assume that the mirror is stronger enough that it could withstand extremely intense X-rays and gamma rays for at least 30 seconds.
Therefore, neither the magnetic nor the electric fields can deflect EM waves.
Hence, the correct option is 4.
