Task: Answer the multiple choice question.
Query: Which drug exhibits a 8.561\% 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(NC1CCN(Cc2ccccc2)CC1)c1ccc(N2CC3CC(C2)c2cccc(=O)n2C3)c([N+](=O)[O-])c1
[b] Cc1ccc(C(C)C)c(OC/C(O)=C(\C#N)c2nc3ccccc3[nH]2)c1
Answer: b. Cc1ccc(C(C)C)c(OC/C(O)=C(\C#N)c2nc3ccccc3[nH]2)c1
