    among the following?
    A Iron Correct Answer Incorrect Answer
    B Aluminum Correct Answer Incorrect Answer
    C Chromium Correct Answer Incorrect Answer
    D Mercury Correct Answer Incorrect Answer

    Solution

    Explanation: Aluminum is known for its excellent electrical conductivity, which is why it is widely used in the electrical industry. It has a thermal conductivity of about 235 watts per Kelvin per meter, making it an effective conductor of both heat and electricity. Although silver is the best conductor among all metals, aluminum is more commonly used due to its availability and lower cost.
