Which statement BEST explains why the student should propose the use of X-rays by the device?
A.
The brightness of X-rays means they last a long time once they are produced by a machine.
B.
The high energy of X-rays allows them to pass through the human body.
C.
The high speed of X-rays allows them to be used safely on human patients.
D.
The rarity of X-rays in nature means they can be used in machines without other X-rays blurring images.

B
X-rays have much higher photon energy (shorter wavelength) than visible light, so they penetrate soft tissue and are absorbed/scattered differently by materials of different density (e.g., bone vs. muscle), producing an internal image. The other choices are incorrect: brightness and rarity aren’t the key reasons, and all electromagnetic radiation travels at essentially the same speed, which doesn’t make X-rays “safe.”
