Task: Answer the multiple choice question.
Question: Which compound has a 4.536\% 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: CCOC(=O)C1=NNC2(CC(=O)N(c3cc(C)cc(C)c3)C2=O)C1
b: COc1ccccc1C(=O)Nc1c(C(=O)N2CCN(C)CC2)oc2ccccc12
c: CC(=O)C1=C(c2ccccc2)NC(=O)NC1c1ccccc1OCC(=O)Nc1ccccc1
d: O=C(c1ccc(Cl)c(S(=O)(=O)N2CCOCC2)c1)N(Cc1nnc(-c2ccccc2Cl)o1)C1CC1
Answer: c. CC(=O)C1=C(c2ccccc2)NC(=O)NC1c1ccccc1OCC(=O)Nc1ccccc1
