Task: Answer the multiple-choice question.
Query: Which compound exhibits a -2.249% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a. CCOC(=O)c1c(C)[nH]c(N=Nc2ccccc2)c1C
b. O=C(O)CC(NC(=O)Nc1ccccc1)c1ccc(OC2CCCC2)cc1
c. CCC(CC)C(=O)Nc1cc([N+](=O)[O-])ccc1F
d. CS(=O)(=O)Nc1ccc(OCc2ccccc2)cc1
Answer: c. CCC(CC)C(=O)Nc1cc([N+](=O)[O-])ccc1F
