Task: Answer the multiple choice question.
Query: Which compound has a 16.007\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a. COc1ccc(S(=O)(=O)N2CCN(c3ccc(C)cc3C)CC2)cc1OC
b. O=C(Nc1nccs1)c1ccc(-c2ccc([N+](=O)[O-])cc2)o1
Answer: b. O=C(Nc1nccs1)c1ccc(-c2ccc([N+](=O)[O-])cc2)o1
