What is the sensitivity range of human eyes to wavelengths of energy in the electromagnetic spectrum?

The sensitivity range of human eyes to wavelengths of energy in the electromagnetic spectrum is indeed between 380nm and 760nm. This range encompasses the visible light spectrum, which is the part of the electromagnetic spectrum that human eyes can perceive.

The lower end of this range, 380nm, corresponds to violet light, while the upper end, 760nm, corresponds to red light. Within this range, different wavelengths correspond to different colors that we can see; for example, blue light has a shorter wavelength closer to 380nm, while red light is towards 760nm. This range is crucial in understanding not only human vision but also how various light sources operate and how colors are perceived.

The other options do not accurately reflect the full visible spectrum, as they either miss parts of the visible range or misstate the upper and lower limits that are perceptible to the average human eye.
