Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -0.203\% 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: O=C(Cn1cc[n+](Cc2ccccc2)c1)c1ccc([N+](=O)[O-])cc1.[Br-]
b: Cc1ccc(SCC(=O)NNC(=O)C2CCCCC2)cc1
c: COc1ccc(S(=O)(=O)N(C)CC(=O)NCC2CCCO2)cc1OC
d: CC(NC(=O)Nc1ccc(F)cc1F)c1ccc2c(c1)OCO2
e: COc1ccccc1CN1C[C@@H]2C[C@@H](C3=Cc4cccc(OC)c4OC3)N3CCC[C@@]23C1=O
Answer: a. O=C(Cn1cc[n+](Cc2ccccc2)c1)c1ccc([N+](=O)[O-])cc1.[Br-]
