Problem statement: Answer the multiple choice question.
Question: Which compound has a 11.284% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a.) O=c1ccc2cc([N+](=O)[O-])c(CCO)cc2o1
b.) O=C(NCc1ccc2c(c1)OCO2)C(=O)NCC1OCCCN1S(=O)(=O)c1ccc(F)cc1
Answer: a. O=c1ccc2cc([N+](=O)[O-])c(CCO)cc2o1
