Answer 1

Answer: (A), (B), (D)

The correct options are
A X-rays are powerful rays that help us to see bones.
B X-rays cannot penetrate through bones.
D X-rays have higher energy than ordinary light.

X-ray has higher energy than ordinary light. It can penetrate through skin and muscles in the body. But the bones do not allow X-ray to pass through them. So the X-ray that we see is the shadow of the bone that gets captured on the plastic X-ray films.
