    • B.

      Mineral

    • C.

      PAG

    • D.

      Ester

    Correct Answer
    A. Alkyl-benzene
    Explanation
    The correct answer is alkyl-benzene because it is a commonly used synthetic lubricant that is compatible with HCFC (hydrochlorofluorocarbon) based ternary blends. Alkyl-benzene lubricants have good thermal stability, chemical resistance, and lubricating properties, making them suitable for use in various applications. They also have low solubility in refrigerants, which helps prevent oil carryover and maintain system performance. Additionally, alkyl-benzene lubricants are environmentally friendly and have a low impact on ozone depletion and global warming potential.
