Problem statement: Answer the multiple-choice question.
Question: Which compound has a -0.657\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: Cc1cc(C)c(S(=O)(=O)c2c(C)cccc2C)c(OCC(C)C)n1
b: CCN1C=C(Cc2ccc(OC)cc2)C2=C(C1)C(c1ccc(OC)cc1)C(C#N)=C(N)O2
Answer: b. CCN1C=C(Cc2ccc(OC)cc2)C2=C(C1)C(c1ccc(OC)cc1)C(C#N)=C(N)O2
