Task: Answer the multiple choice question.
Query: Which compound has a -21.055\% 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: O=[N+]([O-])c1ccc2nc(-c3ccc(Cl)cc3)n(OCc3ccccc3)c2c1
b: COCCNC(=O)/C(C#N)=C/c1ccc2c(c1)OCO2
c: CN(CCc1cnn(C)c1)Cc1cn[nH]c1-c1ccc(-c2ccccc2)cc1
Answer: c. CN(CCc1cnn(C)c1)Cc1cn[nH]c1-c1ccc(-c2ccccc2)cc1
