Task: Answer the multiple choice question.
Query: Which compound has a 1.828\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a. CN(c1ccc([N+](=O)[O-])cc1C(N)=O)C1CCCCC1
b. COCCNC(=O)CN1CCN(C(c2ccccc2)c2ccccc2)CC1.O=C(O)C(=O)O
Answer: b. COCCNC(=O)CN1CCN(C(c2ccccc2)c2ccccc2)CC1.O=C(O)C(=O)O
