Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.416\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: O=c1cc(O)n(-c2ccccc2)c(=S)[nH]1
b: CC1CCCC(C)N1S(=O)(=O)c1ccc(NC(=O)CCn2cnc3ccccc3c2=O)cc1
Answer: b. CC1CCCC(C)N1S(=O)(=O)c1ccc(NC(=O)CCn2cnc3ccccc3c2=O)cc1
