Task: Answer the multiple-choice question.
Query: Which drug has a 8.979% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCOC(=O)C1CCCN(C2=NC(=O)/C(=C/c3ccc(OC)cc3OC)S2)C1
b: CCOC(=O)C1=C(COC(=O)c2cc(OC)c(OC)cc2[N+](=O)[O-])NC(=O)NC1C
c: O=C1CC(NS(=O)(=O)c2cccs2)CN1c1ccc(Cl)cc1
d: Cn1c(=O)c2c(SCc3cccnc3)nc(C3CC3)nc2n(C)c1=O
Answer: b. CCOC(=O)C1=C(COC(=O)c2cc(OC)c(OC)cc2[N+](=O)[O-])NC(=O)NC1C
