Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 12.778\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: CC(=O)Nc1ccc(NC(=O)C(C)OC(=O)c2c(NC(C)=O)sc(C)c2C)cc1
b: O=C1CCCC2=C1C(c1ccccc1O)C1=C(CCCC1=O)O2
Answer: a. CC(=O)Nc1ccc(NC(=O)C(C)OC(=O)c2c(NC(C)=O)sc(C)c2C)cc1
