Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 20.770\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) CC(Sc1ccccc1)C(=O)NN=C1CCCC1
(b) COc1cc(/C=C(\C#N)C(=O)NCC2CCCO2)ccc1OCC(N)=O
(c) COC(=O)COc1nc(C)c2c(c1C#N)CC(C)(C)OC2
(d) COc1cc(C(=O)Nc2ccccc2-c2nnn(CC(N)=O)n2)cc(OC)c1OC
Answer: b. COc1cc(/C=C(\C#N)C(=O)NCC2CCCO2)ccc1OCC(N)=O
