Task: Answer the multiple choice question.
Query: Which drug has a 6.268\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
[a] CCCCn1c(N)c(N(CCOC)C(=O)c2ccc(-c3ccc(C(C)=O)cc3)o2)c(=O)[nH]c1=O
[b] O=C(NCCc1c[nH]c2ccccc12)C(F)(F)C(F)F
Answer: b. O=C(NCCc1c[nH]c2ccccc12)C(F)(F)C(F)F
