Consider the following statements regarding ‘Control Rods of Nuclear Reactor’’

Control rods are basically made up of neutron absorber material which controls the rate of fission of radioactive material by absorbing neutrons.
The most common materials used in control rods are boron, hafnium, and cadmium.

Select the correct statement.

Control rods are typically made up of materials that absorb neutrons. These materials are called neutron absorbers or poisons.
Boron is a particularly effective neutron absorber and is used in many types of reactors. It can be in the form of boron carbide (B4C), boron-10 (10B), or boron-11 (11B).
Hafnium is another neutron absorber that is used in some types of reactors. It is particularly useful because it has a high melting point and is corrosion resistant.
Cadmium is also used as a neutron absorber in some types of reactors. It has a high neutron absorption cross-section and is relatively easy to handle.
Thus, most common materials used in control rods are boron, hafnium, and cadmium.

Hence both statements are correct.
