Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 8.555\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=[N+]([O-])c1ccc(Nc2ccccc2)cc1
[b] C/C=C/c1ccc(OCC(O)CNCC(c2ccc(OC)cc2)N(C)C)c(OC)c1.O=C(O)C(=O)O
[c] Cc1ccc(S(=O)(=O)c2c[nH]c3ccc(C)cc3c2=O)cc1
Answer: a. O=[N+]([O-])c1ccc(Nc2ccccc2)cc1
