Answer:
d. opinions
Explanation: To support evidence of a claim or counterclaim, an author needs to use facts, not opinions. An opinion could show that the author supports or doesn't support the claim, (Or counterclaim) but wouldn't use any evidence to say whether the claim is true or false.
Although both B and C would support the argument, I believe the correct answer in this case would be A.

B because o-le-o-mar-ga-rine
