Task: Answer the multiple choice question.
Question: Which compound has a 1.991\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) COc1ccc(C(=O)OCC(=O)Nc2ncc([N+](=O)[O-])s2)cc1OC
(b) COc1ccc(NC(=O)C2C3C=CC4(O3)C2C(=O)N(CCN2CCCCC2)C4C(=O)NC2CCCC(C)C2C)cc1
(c) COCCn1c(SCCOc2ccccc2)nc2ccccc2c1=O
Answer: c. COCCn1c(SCCOc2ccccc2)nc2ccccc2c1=O
