Task: Answer the multiple-choice question.
Question: Which drug has a -2.139\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) CCOCCn1c(=O)c2c(nc3n2CC(C)CN3Cc2ccccc2)n(C)c1=O
(b) COc1ccccc1NC(=O)C1CCCN1C(=O)Nc1ccc(F)cc1
(c) COc1ccc(NC(=O)CN2CCCC(C)C2)c([N+](=O)[O-])c1
(d) CCOC(=O)/C(C#N)=C(C)/C=C1\Sc2ccccc2N1CC
Answer: c. COc1ccc(NC(=O)CN2CCCC(C)C2)c([N+](=O)[O-])c1
