Task: Answer the multiple-choice question.
Question: Which drug exhibits a 21.903% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
[a] CCOC(=O)/C(C#N)=C/N=c1ccc(C)cn1C
[b] COc1ccccc1NC(=O)Cn1c(=O)c(N(C)C)c(N)n(C)c1=O
[c] COc1ccc(Br)cc1CN1CCN(C(=O)c2ccco2)CC1.O=C(O)C(=O)O
[d] CCCNC(=S)Nc1cccc(C(F)(F)F)c1
Answer: b. COc1ccccc1NC(=O)Cn1c(=O)c(N(C)C)c(N)n(C)c1=O
