Task: Answer the multiple-choice question.
Question: Which drug has a 4.370\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a COc1ccc(C)cc1NC(=O)n1ncc2c(C)cccc21
b COC(=O)C1=C(C)NC(C)=C(C(=O)OC)C1C(=O)OCC(=O)c1ccc(Br)cc1
Answer: b. COC(=O)C1=C(C)NC(C)=C(C(=O)OC)C1C(=O)OCC(=O)c1ccc(Br)cc1
