Task: Answer the multiple choice question.
Question: Which compound has a 17.868% 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: CCOC(=O)C(CC(=O)O)=C(c1ccccc1)c1ccccc1
b: CC1CCCCC1NC(=O)c1cccc(S(=O)(=O)N2CCN(C)CC2)c1
Answer: a. CCOC(=O)C(CC(=O)O)=C(c1ccccc1)c1ccccc1
