Task: Answer the multiple-choice question.
Query: Which compound exhibits a -3.986\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CNC(=O)CN(c1cccc(Br)c1)S(C)(=O)=O
b O=[N+]([O-])c1cccc(CSc2nc3ccccc3[nH]2)c1
c O=C(Nc1ccc2snnc2c1)N1CCN(c2ccccc2)CC1
d CCC(C)Oc1nc(C)cc(C)c1S(=O)(=O)c1ccccc1C
e O=C1C2C(c3ccccc3)C=CC(c3ccccc3)C2C(=O)N1CCO
Answer: b. O=[N+]([O-])c1cccc(CSc2nc3ccccc3[nH]2)c1
