Task: Answer the multiple-choice question.
Query: Which drug exhibits a 7.854% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a O=C1CC(=O)CC(c2ccccc2Cl)C1
b CCCCNCc1cccn1-c1ccccc1.O=C(O)C(=O)O
Answer: a. O=C1CC(=O)CC(c2ccccc2Cl)C1
