In radiography, a radiolucent area indicates what about tissue density?

Explanation:
Radiography shows how much X-rays are absorbed by tissues. Dense structures, like bone, absorb many X-rays and appear light (radiopaque). Less dense tissues absorb fewer X-rays and appear darker (radiolucent). So a radiolucent area means the tissue density is lower than its surroundings (or contains air), allowing X-rays to pass through with less attenuation. The other options describe greater density or mineralization, which would look lighter on the image, not darker, and wouldn’t be radiolucent.
