Bergonie and Tribondeau's law relates cellular radiosensitivity to which characteristic?

Explanation:
Radiosensitivity is greatest in cells that are actively dividing and are not yet fully differentiated. Bergonie and Tribondeau showed that the more mitotically active and less differentiated a cell is, the more sensitive it is to radiation. Therefore, young and undifferentiated cells fit this pattern best, since they are typically rapidly dividing and not yet specialized. Tissues with mature, differentiated, nondividing cells—like neurons or muscle—are comparatively radioresistant, which is why the other descriptions don’t match as well.
