Task: Answer the multiple choice question.
Question: Which drug exhibits a 7.756\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: Cc1cc2nc(-c3cccnc3SCC(=O)NCc3ccco3)[nH]c2cc1C
b: O=C(c1ccc(Br)cc1)c1cc([N+](=O)[O-])ccc1N1CCOCC1
Answer: b. O=C(c1ccc(Br)cc1)c1cc([N+](=O)[O-])ccc1N1CCOCC1
