Problem statement: Answer the multiple choice question.
Question: Which compound has a -18.551\% 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(NCC(O)c1ccc([N+](=O)[O-])cc1)c1cccc(S(=O)(=O)N2CCCC2)c1
[b] COC(=O)CCCC(=O)NC1CCCN(C2Cc3ccccc3C2)C1
Answer: a. O=C(NCC(O)c1ccc([N+](=O)[O-])cc1)c1cccc(S(=O)(=O)N2CCCC2)c1
