With respect to electromagnetic waves, the human eye is sensitive to

Electromagnetic waves consist of oscillating electric and magnetic fields. However, the human eye is primarily sensitive to the electric field component of the wave. In the context of optics, the electric field vector is often called the light vector because it is responsible for the interaction with the photoreceptor cells (rods and cones) in the retina. These cells contain photopigments that undergo a chemical change when they absorb energy from the oscillating electric field, triggering neural impulses. The magnetic field component has a negligible effect on the eye. Option D is incorrect because the human eye is sensitive to the visible light spectrum (approximately 400 nm to 700 nm), whereas the infrared spectrum lies beyond the visible range at longer wavelengths.
