Problem statement: Answer the multiple choice question.
Question: Which drug has a -32.592% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) CC1CCCC(NC(=O)COC(=O)c2cc(S(=O)(=O)N3CCOCC3)ccc2F)C1C
(b) CCOC(=O)N=S(=O)(Oc1ccc([N+](=O)[O-])cc1)c1ccc(Cl)cc1
Answer: b. CCOC(=O)N=S(=O)(Oc1ccc([N+](=O)[O-])cc1)c1ccc(Cl)cc1
