Task: Answer the multiple-choice question.
Query: Which drug exhibits a -5.163% 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) CCOc1ccc(NC(=S)N(CCOC)C(C)c2ccco2)cc1
(b) COc1ccc(NC(=O)CN2C(=O)NC(C)(c3ccc(C)cc3)C2=O)c([N+](=O)[O-])c1
Answer: b. COc1ccc(NC(=O)CN2C(=O)NC(C)(c3ccc(C)cc3)C2=O)c([N+](=O)[O-])c1
