Final answer:
The value of safe temperature is 0 because the food temperature of 50 does not meet the criteria of being less than 40 or greater than 165. The correct option is (1).
Step-by-step explanation:
The question is asking us to assign the value of safe temperature as 1 if the food temperature is less than 40 or greater than 165. Given that the food temperature is 50, we can determine the value of safe temperature.
Since 50 is not less than 40 and not greater than 165, we do not assign the value of 1 to safe temperature. Therefore, the value of safe temperature, in this case, would be 0.
