Task: Answer the multiple choice question.
Query: Which compound exhibits a 5.373\% 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 additional words.
Options:
(a) Cc1cc(C)cc(N(CCC#N)C(=O)COC(=O)CNC(=O)c2sc3ccccc3c2Cl)c1
(b) O=C(NCc1cc([N+](=O)[O-])ccc1O)c1ccc(COc2ccccc2)cc1
(c) Cc1cc(C)c2cc(CN(CCN3CCCC3)C(=O)Nc3ccc(F)cc3)c(=O)[nH]c2c1
(d) O=C1SC(SCc2ccccc2)=N/C1=C\c1ccc(C(=O)O)cc1
Answer: b. O=C(NCc1cc([N+](=O)[O-])ccc1O)c1ccc(COc2ccccc2)cc1
