Answer: The answer is D

D.In hydraulic systems, the operating temperatures must be kept between 170�F and 180°F

Step-by-step explanation:

The operating temperature for hydraulic systems is 140°F and below. Anything above this temperature is too high and will reduce the useful life of hydraulic fluid.

Most often problems associated with hydraulic systems are caused by fluid contaminated with particulate matter.
