Task: Answer the multiple choice question.
Query: Which drug exhibits a 5.430% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
[a] CC(=O)N1CC2(C)CN(C(C)=O)CC(C)(C1)C2=O
[b] COc1ccccc1-c1ccc2nnc(SCC(=O)N3CCCC3)n2n1
[c] CSc1ccc(Cl)c(C(=O)OCC(=O)N(C)CCC#N)c1
Answer: b. COc1ccccc1-c1ccc2nnc(SCC(=O)N3CCCC3)n2n1
