Task: Answer the multiple choice question.
Question: Which drug exhibits a 23.899\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a.) CC(=NC1CC1)C1=C(O)c2ccccc2C1=O
b.) CCc1ccccc1NC(=O)Cn1cccc1C1=NC(c2ccccc2)CO1
c.) COc1ccc(Cn2c(-c3ccc(OC)cc3)nc3c(c(=O)c4ccccc4n3C)c2=O)cc1
Answer: a. CC(=NC1CC1)C1=C(O)c2ccccc2C1=O
