Problem statement: Answer the multiple choice question.
Question: Which drug has a 5.500\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
[a] O=C(CNc1ccccc1Cl)c1ccc(Br)cc1
[b] O=C(COC(=O)CCC1CCCC1)Nc1ccc(F)cc1Cl
Answer: b. O=C(COC(=O)CCC1CCCC1)Nc1ccc(F)cc1Cl
