Task: Answer the multiple choice question.
Query: Which drug exhibits a 0.868% 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 other words.
Options:
a) COC(=O)[C@@H](NC(=O)NC1CCCCC1C)C(C)C
b) O=C(CN1CCC(C(=O)c2ccc(Cl)cc2)CC1)NC1CCCC1
Answer: a. COC(=O)[C@@H](NC(=O)NC1CCCCC1C)C(C)C
