Task: Answer the multiple-choice question.
Query: Which drug has a 17.838\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=C(Cc1ccc(Cl)cc1)Nc1ccccc1C(=O)Nc1ccc(C(=O)O)cc1
b: O=C(CN1C(=O)S/C(=C\C=C\c2ccccc2)C1=O)NC1CCS(=O)(=O)C1
Answer: b. O=C(CN1C(=O)S/C(=C\C=C\c2ccccc2)C1=O)NC1CCS(=O)(=O)C1
