Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 4.828\% 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: O=C(NCCOCCNC(=O)OCc1ccccc1)OCc1ccccc1
b: COc1cc(C2C(C(=O)c3ccco3)=C(O)C(=O)N2CC2CCCO2)ccc1O
Answer: a. O=C(NCCOCCNC(=O)OCc1ccccc1)OCc1ccccc1
