Task: Answer the multiple-choice question.
Query: Which compound exhibits a 13.391\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) C=CCc1cccc(Cl)c1OCCON1C(=O)CCC1=O
b.) CNC(C(=O)c1ccccc1)C(OC(C)=O)c1cccc([N+](=O)[O-])c1.[O-][Cl+3]([O-])([O-])O
c.) CCSC1=NC(C)(C)C=C(/C=C/c2ccc(Cl)cc2Cl)N1
d.) COC(=O)/C(C#N)=C/c1c(N2CCN(c3cccc(Cl)c3)CC2)nc2c(C)cccn2c1=O
Answer: b. CNC(C(=O)c1ccccc1)C(OC(C)=O)c1cccc([N+](=O)[O-])c1.[O-][Cl+3]([O-])([O-])O
