Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.820\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] CCOC(=O)c1c(C#N)cnn1-c1ccc(C)cc1
[b] COC(=O)Cn1cc(/C=C2\C(=O)NC(=O)N(c3ccccc3)C2=O)c2ccccc21
[c] COc1cnc(-c2ccccn2)nc1Sc1c(Cl)cccc1Cl
Answer: b. COC(=O)Cn1cc(/C=C2\C(=O)NC(=O)N(c3ccccc3)C2=O)c2ccccc21
