Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 1.480\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: Cc1ccc(Cn2cc(C=O)c3ccccc32)cc1
b: [Cl-].c1ccc(Cn2c[n+](Cc3ccccc3)c3ccccc32)cc1
c: CN(C)C1(CNC(=O)c2cc(S(=O)(=O)N3CCOCC3)c(Cl)cc2Cl)CCCCC1
Answer: b. [Cl-].c1ccc(Cn2c[n+](Cc3ccccc3)c3ccccc32)cc1
