Task: Answer the multiple-choice question.
Query: Which drug has a 9.428\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a: COc1cccc(NC(=O)CN(c2ccc([N+](=O)[O-])cc2)S(=O)(=O)c2ccccc2)c1
b: COc1cc(-c2nnc(SCc3cc(=O)oc4cc(O)c(O)cc34)o2)cc(OC)c1OC
c: O=C(CCC1CCCCC1)Nc1ccccc1-c1ccccc1
d: N#CCCn1cc(/C=C/C(=O)O)c(-c2ccc(F)cc2)n1
e: CN(CCc1ccccn1)C(=O)CCC1CCCN(C(=O)CCOc2ccccc2)C1
Answer: b. COc1cc(-c2nnc(SCc3cc(=O)oc4cc(O)c(O)cc34)o2)cc(OC)c1OC
