    Enzymatic water temperature of:

    • A.

      140 deg F (60 deg C)

    • B.

      130 deg F (80 deg C)

    Correct Answer
    A. 140 deg F (60 deg C)
    Explanation
    The correct answer is 140 deg F (60 deg C) because enzymatic activity is known to be optimal at a specific temperature range. This temperature range allows the enzymes to function at their highest efficiency, leading to faster and more effective chemical reactions. In this case, the enzymatic water temperature of 140 deg F (60 deg C) is likely to provide the ideal conditions for the enzymes to perform their intended functions. The other option of 130 deg F (80 deg C) is outside the optimal temperature range for enzymatic activity and may result in reduced effectiveness or denaturation of the enzymes.
