What is the correct way to express a temperature interval in degrees Celsius?

[mopar969]

A particular temperature interval, as opposed to a particular temperature value is written (a) C°, (b) °C, (c) degrees celsius minus degrees celsius (d) it makes no difference.

I am unsure as to what the question is asking.

Ooops I forgot to type in the option for c. After reading the link above provided by a PF member It says that options a and b can both be used. Therefore the answer to this question is then D. Is this correct.

It really depends on your instructor or textbook and how fussy they want to be. If you wanted to be as clear as possible, how would you write a temperature interval?

Just to add: Since the question calls attention to a distinction between an interval and a temperature, I suspect they want you to choose which is most accurate. Otherwise why bring it up at all? (But see what your book says.)
