Task: Answer the multiple-choice question.
Query: Which compound has a 1.392\% 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) O=C(O)CC1S/C(=N\N=C2\C(=O)Nc3ccccc32)N(c2ccc(O)cc2)C1=O
(b) CN(Cc1ccccc1)Cc1nc2c(c(=O)n(C)c(=O)n2C)n1CCc1ccccc1
Answer: a. O=C(O)CC1S/C(=N\N=C2\C(=O)Nc3ccccc32)N(c2ccc(O)cc2)C1=O
