Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.004\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
[a] COc1ccc(NC(=O)COc2ccccc2)cc1Cl
[b] Cc1c(NC(=O)/C(C#N)=C/c2ccc(-c3ccccc3Cl)o2)c(=O)n(-c2ccccc2)n1C
[c] COc1ccc(OC)c(Nc2cc(-c3ccccc3)nc(N)n2)c1
[d] COc1cccc(CN(CC2CCCO2)S(=O)(=O)c2ccc(S(=O)(=O)N(C)C)cc2)c1
[e] CC/C(=N\O)C(C)(C)/[N+]([O-])=C/c1ccc(Br)cc1
Answer: b. Cc1c(NC(=O)/C(C#N)=C/c2ccc(-c3ccccc3Cl)o2)c(=O)n(-c2ccccc2)n1C
