Task: Answer the multiple-choice question.
Query: Which compound exhibits a -21.798% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] COc1ccc(-n2ccn(CC(=O)Nc3ccccc3OC)c(=O)c2=O)cc1
[b] O=c1[nH]c(=S)n(Cc2ccc(F)cc2)c(O)c1/C=N/N1CCCCCC1
[c] O=C(CC1C(=O)NCCN1C(=O)c1ccc([N+](=O)[O-])cc1)Nc1ccc(F)cc1
Answer: c. O=C(CC1C(=O)NCCN1C(=O)c1ccc([N+](=O)[O-])cc1)Nc1ccc(F)cc1
