Task: Answer the multiple-choice question.
Query: Which compound exhibits a 6.371\% human ether-à-go-go related gene (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] O=C(NCc1ccco1)c1ccc2c(=O)n(-c3ccccc3)c(=S)[nH]c2c1
[b] C/C(Nc1ccc(C)cc1)=C(/C#N)C(N)=O
Answer: b. C/C(Nc1ccc(C)cc1)=C(/C#N)C(N)=O
