Problem statement: Answer the multiple-choice question.
Query: Which compound exhibits a -18.289\% 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. O=C(CSc1cccc[n+]1[O-])Nc1cccc(S(=O)(=O)NC2=NCCCCC2)c1
b. Cc1cccc(CNc2ncc(-c3cccc([N+](=O)[O-])c3)n2C)c1.O=C(O)C(=O)O
c. O=C(NCC1COc2ccccc2O1)C1CCN(S(=O)(=O)c2ccc(Cl)cc2)CC1
d. NC(=O)c1ccc[n+](CC(=O)OCCC23CC4CC(CC(C4)C2)C3)c1.[Cl-]
Answer: b. Cc1cccc(CNc2ncc(-c3cccc([N+](=O)[O-])c3)n2C)c1.O=C(O)C(=O)O
