Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 11.251% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
[a] O=C(Nc1ccc(Cl)cc1)Nc1ccc(-c2cnco2)cc1
[b] CC1CC(C#N)N(N(C)C)C1=C(C#N)C#N
[c] COc1cc(NC(=O)CN(c2ccc(C)cc2)S(=O)(=O)c2c(C)nn(C)c2C)cc(OC)c1
[d] O=C(NNCC(O)COc1ccccc1)c1ccccc1
[e] CSc1nnc(C)c(=O)n1COC(=O)c1cc(Cl)ccc1[N+](=O)[O-]
Answer: b. CC1CC(C#N)N(N(C)C)C1=C(C#N)C#N
