Task: Answer the multiple choice question.
Query: Which drug has a 13.407\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
a: CN1c2ccc(C=O)c3c(C=O)ccc(c23)N(C)C1(C)C
b: O=C(O)CN1CCN(Cc2ccccc2F)C1=O
Answer: b. O=C(O)CN1CCN(Cc2ccccc2F)C1=O
