Task: Answer the MCQ question.
Question: Which compound exhibits a 13.018\% 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: CN(C)S(=O)(=O)Oc1cccc(C(=O)Nc2ccc([N+](=O)[O-])cc2)c1
b: CC(=O)c1c([O-])n(-c2cccc(Cl)c2)c(=O)[nH]c1=O.C[NH+](C)C
c: O=CNc1ccc(OP(=O)(Oc2ccccc2)Oc2ccccc2)cc1
d: CCOC(CNC(=O)c1cccn2c(=O)c3cc(Cl)ccc3nc12)OCC
Answer: b. CC(=O)c1c([O-])n(-c2cccc(Cl)c2)c(=O)[nH]c1=O.C[NH+](C)C
