Task: Answer the multiple-choice question.
Question: Which drug exhibits a 15.875\% 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(O)c1ccc2c(c1)C(=O)N(c1cccc(S(=O)(=O)Nc3cccc(C(F)(F)F)c3)c1)C2=O
[b] CCOC(=O)c1sc(NC(=O)CSc2n[nH]c(-c3ccc(Cl)cc3Cl)n2)c(C#N)c1C
Answer: a. O=C(O)c1ccc2c(c1)C(=O)N(c1cccc(S(=O)(=O)Nc3cccc(C(F)(F)F)c3)c1)C2=O
