Task: Answer the multiple choice question.
Question: Which drug exhibits a 0.466\% 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(CCn1cnnn1)Nc1cccc(F)c1
b COc1ccc(-c2nc(C#N)c(NCCCN3CCOCC3)o2)cc1
Answer: a. O=C(CCn1cnnn1)Nc1cccc(F)c1
