Can someone please help, answer with steps.

Your Answer Is C) III Only.

A temperature increase of 5/9 degrees Fahrenheit is equivalent to a temperature increase of 1 degree Celsius.

One way we could check is by multiplying (f -32) by five degrees.

( f - 32 ) = 31

9 / 5 = 1.8

31 * 1.8 = 55.8

55.8 / 14^2 = 0.28

Now, let's check,

0.28 / 1.8 = 0.504

0.504 * 28.1232 = 55.8

Or it could be solved by keeping on adding. (That would be easier but I prefer multiplying.)
