Task: Answer the multiple choice question.
Query: Which compound has a -1.807% 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=C(NC1(Cc2ccccc2)CCN(CCc2cccs2)C1=O)c1ccccc1
b: O=C(CNC(=O)c1cccs1)NCC(=O)OCc1ccc(Br)cc1
Answer: a. O=C(NC1(Cc2ccccc2)CCN(CCc2cccs2)C1=O)c1ccccc1
