Question 2741 Deck General

The correct answer is D) 59°Fahrenheit or less. In the context of commercial fishing, "cold water" is defined as water where the monthly mean low water temperature is normally 59°Fahrenheit or less. This definition is based on the regulations and guidelines established by the US Coast Guard for commercial fishing operations. The other options are incorrect because they define "cold water" at lower temperature thresholds, which do not align with the standard used in the commercial fishing industry. For example, 39°Fahrenheit or less would be considered extremely cold water, which is not the typical definition used in this context.
