Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.364\% 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: CCS(=O)(=O)N1CCC(C(=O)NCc2cccs2)CC1
b: CCS(=O)(=O)CCSc1nc2c(cc1C#N)CCCC2
c: O=C(O)CC(NC(=O)COc1ccc(Cl)cc1Cl)C(=O)O
d: CC(C)OCCCNC(=O)c1ccc(NS(C)(=O)=O)cc1
Answer: c. O=C(O)CC(NC(=O)COc1ccc(Cl)cc1Cl)C(=O)O
