Task: Answer the multiple choice question.
Question: Which drug has a 12.752\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1ccc(CNCc2ccc([N+](=O)[O-])cc2)cc1OC.O=C(O)C(=O)O
b: Cc1ccc(C(=O)/C=C/c2ccc(-c3ccccc3[N+](=O)[O-])o2)cc1
c: Cc1ccc(NC(=O)c2cccs2)cc1NC(=O)c1cccc(F)c1
Answer: b. Cc1ccc(C(=O)/C=C/c2ccc(-c3ccccc3[N+](=O)[O-])o2)cc1
