Task: Answer the multiple choice question.
Query: Which compound has a -6.525% 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)C(CC)(CCC(=O)O)c1csc(Nc2ccc(C)cc2)n1
b: O=C1CN(C(=O)COc2ccccc2Cl)c2ccccc2N1
c: COc1ccc2oc3ccc(OC)cc3c(=O)c2c1
d: Cc1ccc(-n2c(SCC(=O)NNC(=S)Nc3ccccc3)nc3ccccc3c2=O)cc1
Answer: c. COc1ccc2oc3ccc(OC)cc3c(=O)c2c1
