Task: Answer the multiple choice question.
Query: Which compound has a 11.543\% 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 CCCCCCc1c(O)nc(SCC(=O)O)[nH]c1=O
b O=[N+]([O-])c1ccccc1/C=N/NC1=NCCN1
c C=CCc1c(C)nc(SC)nc1Nc1ccc(C)cc1
d O=C(NCC1CCCO1)c1ccc(CS(=O)(=O)c2ccc(Cl)cc2)o1
Answer: b. O=[N+]([O-])c1ccccc1/C=N/NC1=NCCN1
