The correct Answer is:
To solve the question regarding the use of cadmium rods in a nuclear reactor, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Function of Cadmium Rods**: - Cadmium rods are materials that have a high neutron absorption capacity. In the context of a nuclear reactor, they play a crucial role in controlling the nuclear fission process. 2. **Identify the Options**: - The options provided are: - (a) Control rods - (b) Fuel rods - (c) Coolant - (d) Modulator 3. **Analyze Each Option**: - **Control rods**: These are used to absorb excess neutrons and regulate the rate of the nuclear reaction. - **Fuel rods**: These contain the nuclear fuel (like uranium) that undergoes fission. - **Coolant**: This is a substance (often water) that removes heat from the reactor core. - **Modulator**: This term is not commonly used in the context of nuclear reactors. 4. **Determine the Correct Function**: - Since cadmium rods are specifically used to absorb neutrons and control the reaction rate, they are classified as control rods. 5. **Select the Correct Alternative**: - Based on the analysis, the correct answer is (a) Control rods. ### Final Answer: The correct alternative is (a) Control rods. ---
