Task: Answer the multiple choice question.
Query: Which compound exhibits a -3.509% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CC(C)[NH+]1CCC2(CC1)C(C#N)=C(N)NC([S-])=C2C#N
b: CC(O)c1nc2c(c(=O)n(C)c(=O)n2C)n1C
Answer: b. CC(O)c1nc2c(c(=O)n(C)c(=O)n2C)n1C
