Task: Answer the multiple choice question.
Question: Which compound has a -6.493\% 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(Nc1ncc(Cc2cccc(Cl)c2Cl)s1)c1ccc([N+](=O)[O-])cc1
b) N#Cc1c(/N=C/c2ccccc2)oc(-c2ccccc2)c1-c1ccccc1
Answer: a. O=C(Nc1ncc(Cc2cccc(Cl)c2Cl)s1)c1ccc([N+](=O)[O-])cc1
