Task: Answer the multiple choice question.
Question: Which compound has a 4.448% 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) O=[N+]([O-])c1cccc(CP(=O)(c2ccccc2)c2ccccc2)c1
(b) CCOc1ccc(/C=c2\sc3nc(-c4ccco4)nn3c2=O)cc1OCC
Answer: a. O=[N+]([O-])c1cccc(CP(=O)(c2ccccc2)c2ccccc2)c1
