Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -8.177\% 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=C1C(Cl)=C(NCCCN2CCOCC2)C(=O)N1CCc1ccccc1
b COc1ccc(NS(=O)(=O)c2ccc(C)c(C(=O)N3CCCCCCC3)c2)cc1
Answer: a. O=C1C(Cl)=C(NCCCN2CCOCC2)C(=O)N1CCc1ccccc1
