Problem statement: Answer the multiple choice question.
Query: Which compound has a -12.853\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: C=CCN(C1CCCCC1)S(=O)(=O)c1ccc2c(c1)oc(=O)n2C
b: COc1ccc(CCN2CC(C#N)=C3c4cc(OC)c(OC)cc4CCN3C2)cc1OC
c: Cc1nc2c(cc1C(=O)/C=C/c1ccccc1F)CCCC2
Answer: b. COc1ccc(CCN2CC(C#N)=C3c4cc(OC)c(OC)cc4CCN3C2)cc1OC
