Task: Answer the multiple-choice question.
Question: Which drug has a 8.771\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] C=Cc1ccc(Cn2nc(-c3ccc(C)cc3)ccc2=O)cc1
[b] O=C(NNC(=O)c1ccccc1Cl)c1ccncc1
[c] CC(Cc1ccccc1)C(=O)NCc1nc2ccccc2s1
[d] O=C(NC(=S)Nc1ccccn1)c1cccc([N+](=O)[O-])c1
Answer: b. O=C(NNC(=O)c1ccccc1Cl)c1ccncc1
