Task: Answer the multiple choice question.
Question: Which drug has a 5.487% hERG inhibition at 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) O=C(c1ccccc1)C1CCc2occc2C1=O
(b) C=CCn1c(O)c(C(C)=NCCCN(C)C)c(=O)[nH]c1=O
Answer: b. C=CCn1c(O)c(C(C)=NCCCN(C)C)c(=O)[nH]c1=O
