Task: Answer the multiple-choice question.
Question: Which drug exhibits a 18.172\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a.) O=C(COc1ccc(OCc2ccccc2)cc1)NN=C1CCCC1
b.) CCOc1cc(/C=N/NC(=O)c2cc(-c3cccc(OC)c3)nc3ccccc23)ccc1O
Answer: a. O=C(COc1ccc(OCc2ccccc2)cc1)NN=C1CCCC1
