Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.277\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a. COc1cc(C(=O)N(C)C2CCCCC2)ccc1OC1CCN(C(C)=O)CC1
b. CC(C)CNc1nc(Oc2ccc(=O)[nH]n2)nc(N(C)C)n1
c. COc1ccc(NC(=O)CCNS(=O)(=O)c2ccc(Cl)c([N+](=O)[O-])c2)cc1S(N)(=O)=O
d. COc1ccccc1-n1cnnc1SCC(=O)Nc1ncc(Cl)cc1Cl
Answer: c. COc1ccc(NC(=O)CCNS(=O)(=O)c2ccc(Cl)c([N+](=O)[O-])c2)cc1S(N)(=O)=O
