    The correct answer is option B which is neutron absorbing material.

    Explanation: In nuclear reactors, uranium absorbs a neutron, broke into two nuclei and releasing 3 more neutrons and energy. These neutrons further absorbed by other uranium atoms. Control rods are used to control the fission reaction in nuclear reactors by absorbing neutrons. Hence the material used in control rods is neutron absorbing material.
