Task: Answer the multiple-choice question.
Query: Which drug exhibits a 24.798% 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) COc1ccc(N(C(=O)C(C)C)S(=O)(=O)c2cccc([N+](=O)[O-])c2)cc1
(b) COCCN1C(=O)C(=O)/C(=C(/O)c2cccc(OC)c2)C1c1ccco1
Answer: b. COCCN1C(=O)C(=O)/C(=C(/O)c2cccc(OC)c2)C1c1ccco1
