Task: Answer the multiple-choice question.
Question: Which drug exhibits a 8.942\% 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] Nc1c(C(=O)N/N=C/c2ccc(OCc3ccccc3)cc2)cnn1-c1ccccc1
[b] O=C1CC(=O)N2N=C(c3ccc([N+](=O)[O-])cc3)SC2=N1
Answer: b. O=C1CC(=O)N2N=C(c3ccc([N+](=O)[O-])cc3)SC2=N1
