Answer:
Option A) The temperature of F degrees Fahrenheit converted to degrees Celsius
Explanation:
The formula to convert temperature from degrees Fahrenheit to degrees Celsius is:

If we have the measure of temperature in degrees Fahrenheit we can convert that temperature to degrees Celsius by substituting it in place of F. For example, if we want to convert 50 degrees Fahrenheit to degrees Celsius just replace F in the above formula by 50 and C(F) will give the equivalent temperature in degrees Celsius.
So, C(F) represents the temperature of F degrees Fahrenheit converted to degrees Celsius. Option A gives the correct answer.
