Task: Answer the multiple-choice question.
Query: Which drug has a 4.335\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: N#CC1(C#N)C(C(N)=O)C1c1ccc(Cl)cc1
b: O=[N+]([O-])c1cc(Br)c(OCc2nnc(-c3ccccc3)o2)c(Br)c1
c: Cc1csc(=O)n1CC(=O)OCC(=O)c1ccc(Br)cc1
Answer: b. O=[N+]([O-])c1cc(Br)c(OCc2nnc(-c3ccccc3)o2)c(Br)c1
