    Correct Answer: Gamma ray


    Solution : The correct answer is Gamma ray.

    Radioactive nuclei emit three types of radiation: alpha, beta, and gamma rays. Alpha rays have the highest ionising power but the least penetrating power. Gamma rays are photons emitted by radioactive nuclei and have the lowest ionising power, which enables them to penetrate more than other types of radiation.
