Problem statement: Answer the multiple choice question.
Question: Which drug has a 13.199\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) O=C(/C=C/c1cccs1)c1cc(Cl)ccc1O
(b) COc1cc(NC(=O)Cn2c([N+](=O)[O-])cnc2C)c(OC)cc1Cl
Answer: b. COc1cc(NC(=O)Cn2c([N+](=O)[O-])cnc2C)c(OC)cc1Cl
