Which of the following statements is true regarding radiosensitive cells?

Radiosensitive cells are characterized by their rapid division rates. Cells that undergo frequent mitosis are more likely to be affected by radiation, as radiation damages DNA and cellular structures. Rapidly dividing cells have less time to repair this damage before they attempt to divide again, increasing their susceptibility to the harmful effects of radiation.

Cells such as those in bone marrow, gonads, and the lining of the gastrointestinal tract exhibit high radiosensitivity due to their ongoing division. This contrasts with the other statements: cells with long lifespans generally experience less damage from radiation because they are not dividing as frequently, specialization refers to cells that perform specific functions and might not necessarily divide often, and liver cells, while they can be radiosensitive under certain conditions, are not exclusively radiosensitive and are not the only type of cells included in this category.
