Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.683\% 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(/C=C/Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1)c1ccc(Cl)c(Cl)c1
(b) CCOC(=O)c1sc(=NC(=O)/C=C/c2ccccc2)n(C)c1C
Answer: b. CCOC(=O)c1sc(=NC(=O)/C=C/c2ccccc2)n(C)c1C
