Task: Answer the multiple choice question.
Query: Which drug has a -19.692% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: COc1cccc(-c2nn(Cc3ccccc3)cc2CO)c1
b: CCOc1ccc(-c2ccc(C=O)o2)c([N+](=O)[O-])c1
c: CC(C)c1cc(C(=O)N2CCCC(C(=O)c3ccc4ccccc4c3)C2)on1
Answer: b. CCOc1ccc(-c2ccc(C=O)o2)c([N+](=O)[O-])c1
