Task: Answer the multiple choice question.
Question: Which drug exhibits a 2.754\% human ether-à-go-go related gene (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] CCCC(C(=O)Nc1ccncc1)c1ccccc1
[b] O=C1CCCc2c1cc(C(=O)Nc1ccc(Cl)cn1)c(=O)n2-c1ccccc1
[c] CC(C)COc1ccc(C(=O)OC2CC(C)(C)OCC2CN(C)C)cc1.Cl
Answer: b. O=C1CCCc2c1cc(C(=O)Nc1ccc(Cl)cn1)c(=O)n2-c1ccccc1
