X-rays are used to produce images of broken bones.

Which statement explains why bones show up clearly on the image?

[1]
A

Bone absorbs more X-rays than soft tissue, so fewer reach the detector behind it

B

Bone reflects X-rays back to a detector, so more X-rays reach it from the bone

C

Soft tissue absorbs more X-rays than bone, so more reach the detector behind bone

D

X-rays travel faster through bone than through soft tissue, so they arrive first
