Answer:
The correct answer is gamma range.
Step-by-step explanation:
A very intense star refers to a bright star exhibiting very high temperature. It is known that hotter the object shorter would be the wavelength of the peak radiation. The ascending order of the wavelength of the given regions in the electromagnetic spectrum is gamma range, then ultraviolet, then visible, and then infrared.
As it can be seen that the shortest wavelength on the basis of the given options is the gamma range, the peak intensity can also be anticipated to fall at that wavelength.
