Task: Answer the multiple choice question.
Query: Which compound has a 8.416\% 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(N=Nc1c(O)[nH]c2ccc(Br)cc12)c1cc(-c2cccc3ccccc23)n[nH]1
b. Cc1ccc(NC(=O)CC2S/C(=N/c3nccs3)N(C)C2=O)c(C)c1
Answer: a. O=C(N=Nc1c(O)[nH]c2ccc(Br)cc12)c1cc(-c2cccc3ccccc23)n[nH]1
