Task: Answer the multiple-choice question.
Question: Which compound exhibits a 1.085% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a) COc1ccc(-c2nc(SCc3ccccc3)n(C(=O)c3ccco3)n2)cc1
b) O=C(Nc1cccnc1)c1cc2c(ccc3ccccc32)o1
c) O=C(c1ccccc1)c1cncc(Br)c1
Answer: b. O=C(Nc1cccnc1)c1cc2c(ccc3ccccc32)o1
