Task: Answer the multiple-choice question.
Query: Which drug exhibits a 17.557% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] CC1CC(C)CN(C(=O)COC(=O)c2ccc3c(c2)C(=O)N(Cc2ccco2)C3=O)C1
[b] COc1ccc(C2NC3=C(CCCC3)C(C#N)(C#N)C2(C#N)C#N)cc1
[c] COC(=O)c1ccc(NC(=O)C[n+]2ccccc2)cc1.[Cl-]
[d] COc1cccc(NC(=S)N2CCn3cccc3C2c2cccnc2)c1
Answer: b. COc1ccc(C2NC3=C(CCCC3)C(C#N)(C#N)C2(C#N)C#N)cc1
