    B Brass Correct Answer Incorrect Answer
    C Forged steel Correct Answer Incorrect Answer
    D Aluminium Correct Answer Incorrect Answer

    Solution

    Solution: Cylinder liners made of cast iron are required in aluminum cylinder blocks. This is because cast iron offers superior durability and wear resistance compared to aluminum. Aluminum by itself may not withstand the high friction and heat generated within the cylinders during engine operation. Hence, even high-quality utility engines use cast iron cylinder sleeves to ensure longevity and efficiency.
