Problem statement: Answer the multiple-choice question.
Question: Which drug has a 4.660\% 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=[N+]([O-])c1ccc(Cl)c(CN2CCC(O)CC2)c1
b: O=C(Nc1ccc(S(=O)(=O)Nc2ncccn2)cc1)c1cnc(Cl)c(Cl)c1
Answer: a. O=[N+]([O-])c1ccc(Cl)c(CN2CCC(O)CC2)c1
