Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 18.632\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: COCc1cc(=O)[nH]c(/N=C(\N)Nc2cccc(Cl)c2)n1
b: CN1C(=O)NC(c2ccc(O)cc2)C2=C1CN(c1ccc(O)cc1)C2=O
Answer: b. CN1C(=O)NC(c2ccc(O)cc2)C2=C1CN(c1ccc(O)cc1)C2=O
