Task: Answer the multiple choice question.
Query: Which compound has a 2.437\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) CCOC(=O)/C=C/C(=O)Nc1ccc(S(=O)(=O)Nc2c(C)cc(C)cc2C)cc1
(b) CC1CC(NC(=O)CC#N)CC(C)(C)C1
Answer: a. CCOC(=O)/C=C/C(=O)Nc1ccc(S(=O)(=O)Nc2c(C)cc(C)cc2C)cc1
