Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.504\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] O=C(CNC(=O)C12CC3CC(CC(C3)C1)C2)N/N=C\c1ccccn1
[b] COc1cc(/C=N/NC(N)=O)c(Br)cc1OCC(=O)Nc1ccccc1C
Answer: b. COc1cc(/C=N/NC(N)=O)c(Br)cc1OCC(=O)Nc1ccccc1C
