Task: Answer the multiple choice question.
Question: Which drug exhibits a -21.557\% 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(NCCCNS(=O)(=O)c2ccccc2)c(Cl)c1
b: O=C(CCCn1c(=O)c2ccccc2n(Cc2cccc(F)c2)c1=O)NC1CCN(Cc2ccccc2)CC1
Answer: b. O=C(CCCn1c(=O)c2ccccc2n(Cc2cccc(F)c2)c1=O)NC1CCN(Cc2ccccc2)CC1
