Task: Answer the multiple choice question.
Query: Which compound exhibits a 10.038\% 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(NC1CCCCC1)c1ccccc1NC(=O)C1CC(=O)N(c2ccc(Cl)cc2)C1
b: O=C(Nc1nnc(-c2ccncc2)o1)c1ccc(Br)s1
Answer: b. O=C(Nc1nnc(-c2ccncc2)o1)c1ccc(Br)s1
