Problem statement: Answer the multiple-choice question.
Question: Which drug has a -4.604\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CCOC(=O)/C(C#N)=C1/SC(C)C(=O)N1c1ccc(Br)cc1
(b) CCc1cc(C(=O)NC(C)C2CCCO2)cs1
Answer: a. CCOC(=O)/C(C#N)=C1/SC(C)C(=O)N1c1ccc(Br)cc1
