Task: Answer the multiple choice question.
Query: Which drug exhibits a 15.037% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) O=C1NC(c2ccccc2O)Nc2ccccc21
(b) COc1ccc(C2CC(=O)C=C(NCc3ccc4c(c3)OCO4)C2)cc1
Answer: a. O=C1NC(c2ccccc2O)Nc2ccccc21
